Safari 15 and 15.1

I've been having issues with Safari browner and pinned tabs for a few months now. I tried to unpin and delete a tab but every time I reboot it brings back those deleted tabs. I thought the update to 15.1 would fix it. I can't even pin new tabs because they disappear. I have reinstalled Monterey. I have deleted all history and cookies and nothing is working. I logged into a different user account and that Safari has no problems. I ran a malware scan and still nothing. This is very frustrating. I've googled and googled to find someone with the same issue but I can't find anything! HELP!
