Hey again! Okay so a few things to check:
What do you see in System Preferences > Users and Groups > Login Items? There could be an app opening automatically causing an issue, if so you can test by removing it “-“ and restarting.
It could be the permissions of your home folder need to be repaired:

In this can in Finder > Go > Home, then hit Command i unlock and apply permissions, restart when done and test.
There could also be files active in your user library that are causing an issue, these are usually installed by third party apps, but I’d say better to try the previous steps.
It could also, however be a setting that needs to be changed. Id check in System Preferences > Accessibility, and also in Security and Privacy > Privacy > Accessibility, you can also remove apps from there and restart.
Also in the security settings is firewall turned on? If so can you disable it and test?
Worst comes to worse, you can rebuild your user profile, it typically only takes a few minutes just let me know how those steps don’t work and if need be I’ll give the steps to rebuild (Usually not necessary). Good luck!
