Ventura Beta 2 System Settings Window doesn't appear

I installed the Ventura Beta 2 update when it came out and for a few days everything was working ok. I shut my M1 Max MBP down and when I restarted the System Settings window no longer appeared. I can select System Settings, it's menu appears as though it was running, but there is no window and it continues to show as running until I shut it down. System Settings works on two other accounts on the same machine, just not in my primary account. I have started in Safe Mode, deleted some plist files that seem to affect similar complaints in older MacOS versions, but the SS window just doesn't appear in this one account. I reported it through Apple Feedback over a week ago but have had no response. I can delete the account and restore it from a backup, but I would REALLY like to figure out what caused this to happen and if it can be fixed by dumping some appropriate (and corrupted) plist or similar file. I would appreciate it if anyone could point me in a direction to try to solve this issue.
