I think my solution from a few years ago still works. It looks like TurboTax has not fixed whatever the error is in the C:\Users\<your-user-name>\AppData\Roaming\Intuit\TurboTax subdirectory, so the directory must be renamed (or possibly deleted?) before you try to open TurboTax again.
I was having the same issue with no help from Turbo tax support. They are clueless and I won't be using them next year.
I did the below and it finally worked. Why Turbo Tax support doesn't know this is beyond
me.
To recap, here is the solution (on an Windows 10 or Windows 11 system):
Step 1: Open File Explorer and go to: c:\users\<your-user-name>
Step 2: Select the View menu and check "Hidden Items" (so that you can see the AppData subdirectory)
Step 3: Go to C:\Users\<your-user-name>\AppData\Roaming\Intuit\TurboTax
Step 4: Rename the TY19, or TY20 or TY21 or TY22 directory to TYXX
Step 5: Open TurboTax again
