According to recent answers provided by ISRO to questions about missions slated for execution in 2020 it seems RISAT-1B is planned for launch this year ahead of RISAT-1A. No details about mission number but if we assume launch mass is similar to RISAT-1 launched in 2012 then this will be a XL launch.
EDIT: (August 2020) RISAT-1A may be getting launched before RISAT-1B after all.

From the government annual (2020/2021) report (pdf attached
here), pp. 23-24. The description matches that of
RISAT-1A.
EOS-04: EOS-04 is a repeat Satellite of RISAT-1 and is configured to ensure continuity of Synthetic Aperture Radar in C-Band providing Microwave data to the user community for operational services. The satellite has the capability to operate in day, night and all weather conditions with a Mission life of 5 years and provides imaging data for various applications related to Land, Water and environment which find useful inputs for Agriculture, Forestry and Water resource management.
From page 60:
Future Missions of PSLV that are slated for launch in 2021 includes PSLV-C51/Amazonia-1, PSLV/EOS-04, PSLV/EOS-06.
In the
TOI article
Isro aims for 7 more launches from India in 2021, updated March 12, launch is scheduled in July.

Will this launch go ahead, on-schedule, despite
today's loss of a GSLV MkII? We shall see.
The GSLV MkII third stage is not used aboard PSLV--no hardware or software commonality? ISRO may choose to review launch campaign processes.

^^ PSLV launch campaign takes a minimum of 45 days so we can rule out any launch this month. I would put this launch as NET mid-October. Also RISAT-1A is a very large and complex satellite, i remember the original RISAT-1 went through extra ground tests before launch so that may also delay this launch further.

[dated November 1 IST]
The assembly of the Polar Satellite Launch Vehicle (PSLV), which is due to launch an earth observation satellite (EOS) in the third quarter, has been stopped at the Satish Dhawan Space Centre, Sriharikota range, according to reliable sources.
Engineers were tight-lipped when asked for the reasons for the standstill. Sources said that the first stage of the rocket had been assembled and they were awaiting directions to proceed further.

On August 4, Union minister of state for space, Jithendra Singh had told Nama Nageswara Rao in Parliament that the PSLV rocket, numbered C52, would launch EOS-04 in the third quarter.

Launch delayed into 2022?
Belated cross-post:
Nobody in India is covering the launch delays?
Especially if launch processing at Sriharikota has halted, either on orders from ISRO, or as some kind of strike?
Looks like flooding in Andhra Pradesh is the current issue perpetuating the launch delays:
After Covid, Andhra floods stall Isro’s sat launch missions this year [dated Nov. 22]
After the Covid pandemic cast a shadow over Isro’s mission launches for over a year, now it is the flood situation in Andhra Pradesh that is stalling satellite launches at the SHAR launch centre in Sriharikota, a barrier island located in Nellore district of the state.
Isro sends key satellites and rocket components from its centres in Kerala and Karnataka to Sriharikota by road for assembling and launch. As many arterial roads in Nellore have to be closed due to the floods, Isro is not able to finalise its launches.
Isro chairman K Sivan told TOI, "We have been working on three launches, including the small satellite launch vehicle (mini-PSLV) launch, before the year ends. But due to heavy rain and floods in Andhra, we have to reassess the situation... We can decide on the three launches only when the flood situation improves."
No news for a month?

Cross-post:
Looks like technical problems have continued to plague all three upcoming ISRO missions:
Teething troubles with indigenous tech cause for delay in 2 Sat launches; humidity halts SSLV [dated Dec. 1] (bolds mine)
Teething troubles with multiple indigenous modules on one satellite and domestic mirror fabrication on the other are major causes for delay in the launch of two Earth Observation Satellites (EOSs) Isro had in its pipeline, while increased humidity has put on hold a key process on the first small satellite launch vehicle (SSLV) mission.
TOI had reported earlier that Isro was hoping to launch three Earth Observations Satellites (EOSs) — two of them (EOS-4 or Risat-1A and EOS-6 or Oceansat-3 using PSLV and the third, EOS-2 or Microsat as part of the first developmental flight of the Small Satellite Launch Vehicle (SSLV) — in the last quarter of 2021.
A senior scientist from Isro headquarters told TOI that Risat-1A got into serious technical issues after more than 20 TR [transmit and receive] modules fabricated indigenously for the first time failed ground tests.
"...When so many modules fail ground tests, unless we understand the criticality of the problem, we cannot go ahead and launch. The satellite could have gone to waste if we went ahead and we had Rs 700 crore at stake. Also, with 5G coming, the frequency of the satellite had to be changed to prevent interference. These are the reasons for delay. Now the technical issues have been addressed and we will start preparations for the launch soon," the scientist said.
TR modules refer to transmit and receive modules that help in telemetry and tracking of the satellites, and another scientist said that the Risat-1A has around 400 of these.
The above could also be the reason for the earlier reported halt assembling PSLV C52?

Cross-post re: PSLV C53:
According to an article in Telugu published January 3, PSLV C53 with Oceansat-3 should launch from First launch Pad on January 20 or in February if the satellite is delayed.
Will the C53 launch proceed first, from FLP?
Or is C52 launching from SLP, before or after C53?

At some point (presumably now NET 2022 since COVID19 delayed the space centre's timeline) they plan to shift all PSLV launches to using the new infrastructure attached to FLP. This allows GSLV family to have a higher flight rate from SLP.

Defence Research and Development Organisation (DRDO) developed Monolithic Microwave Integrated Circuits (MMICs) have been used in radar imaging satellite modules of EOS 04, which was launched by ISRO on 14th Feb 2022. Many of the Monolithic Microwave Integrated Circuits (MMIC) were designed/ developed and produced at Solid State Physics Laboratory (SSPL) DRDO and Gallium Arsenide Enabling Technology Centre (GAETEC) foundry of DRDO.
The TR-Modules used in the payload for Radar imaging have been developed using these MMICs. More than 30,000 modules have been produced at GAETEC foundry for various space missions. This is an example of collaborative achievement between two advanced technology departments of Government of India along with support of industry partners. The use of indigenously designed and developed MMICs is an important step towards Atmanibhar Bharat.
