Insert/spacebar not working after start up

Hello,

Recently ive been encountering a rather annoying bug. Everytime i first start up my game and enter a room, i wont be able to jump. I have to go to control settings and set my spacebar again and then it works.

Onto the most annoying thing, i want to get rid of my teammates names in my screen and the A/B signs + the C4 sign in S&D matches, but my insert button wont work to do it, i cant open my map either or close my mini map with the delete buttons. I dont think the bug is caused by my keyboard because the buttons function properly.

Is this a known error and is there a fix for it?

Thanks in advance.
