Android Question data base not working

It is very hard to imagine a change in an Android version that would affect just one column in a database. There is almost certainly some other factor involved. As you can see, nobody has come forward yet to help you. That is probably because you are providing no clues, only your own opinion of the cause.

As is often suggested, the "How to post ..." item at the top of the forum is worth reading. Start by posting the full error message and the section of the code where the error occurs.

We can't do anything if we don't have more information.

You mean SQLite? Where do you store it? (Path)

I upload the database with Android 11 and download it from the server with Android 8, and when I save it, it gives an error

If you don't show an example and the error message, we can't do anything.
Click on file and export in zip. Post the zip and the log.
