MacOs Safari 14 freezes when adding page to Bookmarks or Reading List

I've tried to reinstall macOs but that didn't resolve the issue.

I also reinstalled macOs from scratch and Safari worked fine, but when I migrated data from my Time Machine it started freezing as before. Therefore I just reinstalled macOs from scratch, installed all apps and moved files manually. This resolved all issues.

Looks like something in my own files/apps was breaking Safari even thought I tried to run it in Safe Boot.

Also, please see Logs for when adding to a Reading List:

You can see that there is a 10 sec delay after first 7 logs and that's the time it freezes for before adding page to a Reading List.
