MacOS Catalina Verifying app at bootstrap I updated to Catalina yesterday and now I have the following message:

every time I turn on my macbook. Until it finishes, I can't open any app.
I've already tried:
sudo xattr -d com.apple.quarantine /Applications/Docker.app

and the output is:
xattr: /Applications/Docker.app: No such xattr: com.apple.quarantine

I have the same problems with other apps like Xcode, Spotify, iOS runtime 11.0 and so on.
I've never encountered this error before.
Should I just wait an hotfix by Apple or do we have a workaround for it?
Update:
I contacted the Apple Support and they suggested me to perform a first aid on the HD and re-install the OS. Both didn't work.
Temporary workaround

(This reduces the security of macOS so it's just temporary)
I also met the similar problem. I contacted Apple technical support and got the reply that I should try Reset NVRAM or PRAM or RESET SMC. But It does not work at all.

Finally I erased the disk, reinstalled macOS Catalina and then recovered important data from Time Machine and other backups. https://support.apple.com/en-us/HT204904
