Which version was installed before?

[NotebookPaper]

"ApplicationVersion": "12.3.1"

Also, windows user account was migrated right before this started to occur.

"The computer will enter the migration phase silently and become sluggish while it moves your user profile from John.Doe to Doe12345. This will cause another reboot."

If you upgraded from 12.3.1 then it don't even have any backward compatibility codes there.

Same error, when trying to generate thumbnails for mkv file.

System.NullReferenceException: Object reference not set to an instance of an object.

   at ShareX.MediaLib.VideoThumbnailerForm.<>c__DisplayClass12_1.<btnStart_Click>b__0()

edit - it seems any mkv, webm and h.265, vp9 video causes this error

Getting the same problem after 2 days ago. Tried uninstalling, reinstalling, deleting config files etc. It just won't open and no log files ever get made.
