I never came across this issue on OSX its only since I’ve been using Windows 11 fulltime.
Basically when using the app I sometimes hit the Windows key between CTRL and ALT and the start menu pop-ups sometimes (thats fine), but then once back focused on the Figma desktop app, many keys stop working e.g. “X” “C” “V” “CTRL” “H” … just a bunch of random keys won’t respond.
At first I thought it was something to do with a conflicting app I had installed, but it seems quite odd as I have a pretty clean/fresh build of Win11 with not many apps installed.
Figma version: 124.2.9
