How often are satellites damaged by Solar Flares?
Infrequently, but above a threshold, pretty severe damage, up to and including failure, are known.

The solar activity also sent several deep-space missions into safe mode or complete shutdown and destroyed the Martian Radiation Environment Experiment aboard NASA's Mars Odyssey mission. At the height of the storms, astronauts aboard the International Space Station had to take cover from the high radiation levels, which had only happened twice before in the mission's history.
The SpaceX Starlink of Feb 3, 2020 is the only one where satellites failed due to drag upon a
normal launch, as far as I know.
https://en.wikipedia.org/wiki/March_1989_geomagnetic_stormSome satellites in polar orbits lost control for several hours. GOES weather satellite communications were interrupted, causing weather images to be lost. NASA's TDRS-1 communication satellite recorded over 250 anomalies caused by the increased particles flowing into its sensitive electronics.[6]

I couldn't find a link to a list or graph from a primary source. Yes, I'm lazy, watching the SuperBowl.
