I have the same problem, @htgreen3, on the same type of system - Surface ARM chipset, Win 11. I've tried the same things, including your suggestions, @mesquitebean. I've had TTax installed for over a month and nearly finished my taxes. I'm guessing this was either a TTax or Windows update that caused a conflict with the ARM chipset. It's not the first time I've run into a problem with the ARM chipset compatibility. Sure hope this gets fixed quickly!
