One of my files may have gotten corrupted during data transfer. Now when RedNotebook reads it, it crashes. If I remove the file from the directory RedNoteBook reads the files like normal.

To Reproduce

1. Add file to directory
   2024-10.txt
2. Start RedNoteBook
3. Select Directory
4. RedNoteBook Crashes

Expected behavior
The program starts normally or at least give an error of the bad file.

Thanks! I agree, corrupted files should not cause RedNotebook to crash. Instead, the corrupted file should be renamed to 2024-10_corrupted.txt, RedNotebook should start normally and an error message should be shown to the user telling them that "Month file /path/to/2024-10.txt could not be loaded, so it has been renamed to /path/to/2024-10_corrupted.txt. We recommend to close RedNotebook and manually copy parts from /path/to/2024-10_corrupted.txt to /path/to/2024-10.txt using a text editor."
