'NoneType' object has no attribute 'get' on 1 file

[Memesgraveyard]

Describe the bug:
Was working on an osp-file I've had for around 6 months, when I wanted to see something on another file. My OpenShot version only allowed one file opened at a time, so I saved file #1, and opened file #2.

After 5 minutes, saved file #2, and attempted to opened file #1 again through OpenShot>File>Open Recent and received error 'NoneType' object has no attribute 'get', which would load nothing.

I closed OpenShot and found the file in my documents folder and opened this way. Same error 'NoneType' object has no attribute 'get', however the silhouette on the mini-timeline showed files. No thumbnails in Projects or main Timeline showed, and file cannot be played.

Load file #2, which works fine.

Restarted PC, same error with file #1.

Looked up error on Google and found someone reloaded thumbnails by deleting C:>Users>Username>.openshot_qt>thumbnail folder. Attempted this but same error, no change

Another user resolved by opening file in Notepad and deleting lines with "null". Deleted 2x lines and saved. New error when opening in Openshot showed that file didn't exist. Re-opened file in Notepad and replaced the deleted "null", which reverted back to the previous error.

Attempted to use debugging report process. However, after deleting the two .log files, the system has not re-created logs even after enabling Debug Mode (Verbose), so I don't have any log files to upload. I can save the osp-file as a .txt file for reference.

Steps to reproduce the behaviour:

1. Find osp-file in Documents folder and open
2. Openshot attempts to load file
3. Fails to load. Error 'NoneType' object has no attribute 'get'

Expected behavior:
Osp-file to load with thumbnails and timeline.

System Details:

• OpenShot Version v3.1.0 : {{ log_context.openshot_qt_version }}
• Operating System / Distro: Windows 10 Pro

Log Files:
Unavailable.

Also, just playing around inside the program. Under Project Files > Video (not "Show All") the video files appear but thumbnails missing. Also, when I drag+drop one into the timeline, thumbnail shows "?" and it still cannot be played. I can pull JSON data from all files though if that can help?

Another note: file #2 that I previously mentioned uses the same video files, and is working (very different projects focusing on different scenes).
