Since the release of 24.02.1, I've had issues in opening a saved file that I've created same day. After closing application and restarting it, selecting to open file in question, it is listed as incorrect and no backups are successful loading either. This results in hours of lost work. This situation had not occurred until after using this new version of kdenlive so this is a new situation for me and have not made any changes on how I have done work from prior to now.


STEPS TO REPRODUCE
1. Open kdenlive and work with sound clips. 
2. Go to File > Save > type in a name for the file (eg. P5R-23). Confirm the name of file and save.
3. Close program
4.  Re-open program
5.  Go to File > Open > select file on computer


OBSERVED RESULT
error indicating the file is incorrect and to open up a backup file which does not load either.

EXPECTED RESULT
File opening correctly.
