unable to convert the file with your version of twinmotion

I have a file that I have been working on for months, I started working on version 2023.2.4, when version 2024.1 came out I installed it and changed the version of the file to 2024.1. I worked with that file in that version for a while with no problem. Today when I go to open it the error appears that it cannot convert the version of the file because it does not have a version, it is impossible since I have been working with that file for a long time, I would like it to be solved as soon as possible. I have the file in my computer storage and it has never been moved or anything like that.
