When Opus tries to read metadata of any .avi file on my system it never finishes, the file handle gets stuck as open and some side issue occur (all label icons are not rendered anymore, same for the metadata of any other video file). A restart of the process solves the issue.
Explorer has no problem with these files.
This issue has persisted after Windows 10 version upgrades, video driver updates, codec updates and codec settings changes to try and set Microsoft default codecs for AVI. This later change sort of improved things, as the issue would not occur simple upon navigating to a directory with AVI files as it did before, but renaming an AVI file is then enough to trigger the issue (in Explorer I can rename them fine and no issue happens).
I have Windows Media Player disabled with "Turn Windows features on or off", but early this year, when trying to solve this issue, I enabled it to try what it said on this FAQ and it did not make a difference.
If any dump file be analyzed, I would rather it be to investigate this problem instead of the help file problem, as this is a lot more annoying to me.
Let me know if you will take the case, so I can prepare and send some dumps. (Should they be taken before and after the problem is triggered or only after?)
