Logic Pro X Crash

Hi there

I experienced my Logic 10.6.1 crashing from time to time when using either the Logic stock sampler or also the UAD Realverb Plugin... I already deinstalled UAD Plugins and did of course do the basic steps such as restarting my computer, etc.

However, I don't really want to set back my Logic or even worse reinstall it, since this would make me loose my settings which I did through all the years... Honestly I also do not think that this is the issue, since everything else runs super smooth...

Thank you in advance.

PS: I am using OS Big Sur11.0.1
