it appears one or more accounts have been deleted. must add accounts again

this is the THIRD time this has happened to me in the two months. I do an update. Quicken crashes (running win11). and then I open it again, run an update and it tells me it can't update any of my bank accounts (across multiple banks and credit cards) because "it appears one or more accounts have been deleted). Except for my investment account. So I wind up having to reconnect all the bank accounts which is a pain. this time I tried uninstalling and reinstalling quicken. but it got worse, I now am getting cc-501 errors for all accounts the first time. then I still have to reconnect all accounts the second try. it's really getting more than annoying. PLEASE help!
