I have the same problem.
I used the solution
Error 190 when opening file in TurboTax Desktop
I got the same error again.
The recommended fix did NOT work.
My thoughts:
1. I have 2021, 2023, and 2024 installed. Do I need to backup *.tax files and use only 1 at a time?
2. Could the *.TAX files be damaged?
3. I may need to manually amend years 2021 and 2023. (Redline the PDF, and make a note, then submit to IRS.
Not many options.
