How do you fix a BattleEye bug in Fortnite?

Can someone help me every time I go into a round in Fortnite I get kicked out within about 2 minutes and it says: "You were removed from the match due to a BattlEye error: Corrupted Memory # 0.

I already reinstalled the game, but it didn't work.

If you've already reinstalled the game, you could still try reinstalling BattleEye.

Otherwise it may be your graphics driver, try to bring it up to date, if that doesn't help, maybe try a downgrade to an older driver version

Do you mean a NVIDIA downgrade right?

Yes exactly

Also didn't work, even set up the PC again, but didn't work either.
