Unfortunately, if you have file corruption, the only one that can do anything is you.

If you have a windows PC, see if your project folder has backups enabled, (right click on the file in file explorer and choose Restore Previous Versions).

If not, and your autosave is also bad, and you didn’t keep backups, there isn’t much that can be done. I’d strongly recommend using Github going forward. How to backup and maintain your project using GitHub and GitHub Desktop [GDevelop wiki]

but this happened before and i was able to open it
