After Bitdefender does an update, apps stop responding

I keep looking for answers to this but only seem to find general answers, not answers to this only happens after a Bitdefender update.

My Win11 laptop works perfectley fine with Bitdefender: Total Security until Bitdefender does an update and reboots my laptop. Then many apps take minutes to open, some don't open at all and if I try to shut down my laptop, nothing happens. I can try several times to shut down and finally have to resort to the forced shut down (power button pressed). It basically makes my laptop unusable.

Why?
