I was able to import a QBO file with a quickbooks 2020 version after getting the error and trying different things.

Follow this article.

Backup your old fidir.txt file from the resource folder. Copy the one from 2023 QB desktop version from the link. Replace your old QBXX version with the 2023 version. Restart QB and it should work.

Actually this article helped me solve the problem:

I downloaded the 2023 fidir.txt and replaced my old 2020 fidir.txt file.

Once it starts working, never allow automatic updates or check for any updates
