2022, April 18 ... ISS EVA-52Although numbered EVA-52, according to this NASA infograph this was the 60th EVA performed in Russian Orlan space suits Any idea how the counting really works ?It looks like the April 28, 2022 spacewalk will be the " 250th spacewalk outside the International Space Station " ?!

(The Cosmonaut Training Center has a page of all Russian VKDs, in Russian (Google English translation link); unscheduled is "Внеплановый", Vneplanovyi.) Roskosmos lists the 18 April 2022 VKD as the 60th Russian VKD, but the 52nd planned one.
