So.
I tried all suggestions and gave up on turbotax on Windows 11.
After a windows 11 update, I did a fresh install and the program worked for about 2 weeks. Then it dies.
Fortunately, I have a decommissioned windows 10 computer that worked just fine.
Transferred all the files and finished all but 1 tax return.
I will have till November 2025 to finish the last one when support for windows 10 ends.
In my opinion, the problem seems to be with the activation of the software since you have to have a online account to authorize the use of turbo tax. You cannot just enter the subscription code onto the computer. So the program needs to be able to verify the authorization online.
