What to do if when I press F or C the discord crashes?

it started with the fact that I remembered a joke, and I wanted to write to the channel on memes,and there I had to click on F and C(sorry, I'm from Ukraine,so we have here instead of F and C the letters F-A and C-C), I wanted to write, I click, discord crashes, and so 15 times, who knows what to do?
