Unexpected Error

[Major5686]

I am trying to use TurboTax Premier via a Desktop download in Windows 11. Each time I load my TT program, a message entitled, Unexpected Error (no error number shown), followed by, "System.Runtime.Serialization... ."pops up. When I click OK the message goes away after a few seconds, and the program seems to open OK. However, while doing my taxes, just prior to the review section, when I responded to the TurboTax screen which said (paraphrasing), ...before we do a review let's check for updates... . At that point the Unexpected error msg popped up again, but everything froze, as in nothing works. I cannot move forward or back. I only hear a soft beep when I try to click on anything. I can use Task Manager to get out of TT and go back and start over again, but once back inside TT I get the same "Frozen" result each time. I am stuck and need help to resolve this error problem.

1) First reboot your computer

2) then Try downloading and installing the Manual Update. Takes some time, so be patient
