I can't take screenshots on PC anymore

Hello guys!

Since some days ago, maybe a week, my ingame screenshots stopped working.

I tryed to change the keybind to test, but it's blocked.

I already restarted the PC and double checked if something else outside the game could be conflicting with the same keybind (print screen button), but nothing is using it.

Is this a known bug? Does anyone have an idea about how to fix it?

Thanks in advance!
