Error (0xC0000005) occurred in thread 0x91C

I've been getting this error sometimes when I go into Thumbnail view:

The error (0xC0000005) occurred in thread 0x91C at address 0x00007FFFFB99349D.

Please help! I can't use this program anymore because it keeps crashing.

(Please keep swearing out of the forum. People read it at work.)

If you started seeing the problem after the recent Windows updates, it's probably caused by a Windows component involved in MP4/MOV files which now seems to be crashing.

Possible workarounds and other advice can be found in this thread:

Thank you for this. I've disabled the "Generate Thumbnails" option under the "Movies" plug-in and that seems to be a good workaround. Thanks again for the help!
