Bitdefender causes windows to crash

On two different PC, Windows 10 and Windows 11. On Windows 10 I had to reinstall Bitdefender and then windows crash. On windows 11 machine I Installed Bitdefender Plus and when restarted PC Windows crash.

Both PC must be reinstalled. This is not very good. I dont want to use Bitdefender anymore now. I have it on another Windows 11 machine but I may chenge to another supplier...

Is this something that you are aware of?
