[2021] [Connectivity/Multiplayer]Problems with Battleye

I can't play a match since a few days. It always shows me the following message:

Removed from match

Rainbow Six Siege errorcode: [2-0x00019008]
[8c5964d841b7796c]

You have been kicked out of the game by Battleye. Reason:
Corrupted memory

I already tried reinstalling the game, resetting my pc and updating the bios. Nothing worked for me. Does anyone have an idea what may cause this issue?
Thank you
