Big Sur Upgrade completely destroyed my user

People at Apple apparently are not capable of writing stable code. After Big Sur update I started getting this

Code Block
0   CoreFoundation            0x00007fff204976af exceptionPreprocess + 242
1   libobjc.A.dylib            0x00007fff201cf3c9 objc_exception_throw + 48

7   CoreData               0x00007fff25ad2821 developerSubmittedBlockToNSManagedObjectContextPerform + 161


Does anybody know what is ACDDatabase, where to find it and how to fix this. Cause I am completely locked out of my Mac account now and apple support is useless.

Error is

Hi, Did you figure out to fix this issue. We are facing the same issue.
