Some thumbs are grey/corrupted if you use time offset in thumbnail settings. Set that to 0 until the problem is fixed. With offset % it should work. If not, give a torrent link for a file that doesn't work.

I get it.

Need to set administrator permissions to full control to
HKEY_CLASSES_ROOT\.mkv\ShellEx\{GUID 1}
HKEY_CLASSES_ROOT\.mkv\ShellEx\{GUID 2}

Next,delete it's

And dk this above with \.mkv,

And delete it too.

Next, start codec tweak tool from k-lite, thumbnails, and set mkv, apply.

All done. Lost MKV thumbnails  E_ua_110

Normally, these keys should already have full access set for administrators. Some other software may have messed with the permissions.

Yes, if thumbnails is showing good.
But in my case, I have 'undefined record' without administrators. And this key was be RED, non-edit color
