I just received 630 error using 2022 software, Rep had me show hidden files and rename folder. I did NOT have to uninstall/reinstall software. Also did not have to reboot.
Steps I followed:
I opened File Explorer: I went to c:\users\myname
I went to the View menu and deselected "Hidden Items" (so that I could see the AppData subdirectory)
I went to C:\Users\myname\AppData\Roaming\Intuit\TurboTax
I renamed TY22 to TY22-old
I entered the license code and it worked.
