I notice that i can't use any signs or use sprint. I tried to look for solution on google but not thing good.
I also tried to verify the game, restart or use the bomb but nothing work.
Help me pls! Thank.

have you tried reinstalling? or maybe it's your controller/keyboard setup?

Yeah but for a few time later, same problem again.

One of my first posts

For those who had the same problem: re-setting the controls to default fixed the issue.

Hope this helps
