XYplorer Beta Club

I'm having a perplexing issue I encountered while trying to get video previews working.
I'm using Windows 10 Pro x64 and XYplorer 20.90.0100.

I installed K-Lite Codec pack and the video controls showed up on the Preview panel. I can hear the audio but the video will not display. If I switch to the Raw View tab and back, there is an artifact of the Raw View where the video should be. The floating and fullscreen preview will only show a single still image and no audio.
I then tried using the "fresh;" mode to see if a clean slate would fix my issue and it mostly did. The preview tab and preview pane would display the video, however the floating preview and fullscreen preview still only show a still frame from the video and no audio. It was at least something, so with that in mind I moved my ".../APPDATA/Roaming/XYplorer" folder to get a fresh config going but the issue still persisted.

Then I noticed that after a while the "fresh;" command instance would stop showing the video also. Closing it and spawning a new one would not fix the issue either. BUT if I closed all instances of XYplorer, then deleted my ".../APPDATA/Roaming/XYplorer", opened XYplorer and then spawned a new "fresh;" instance then that one would display the video preview. I have done this 10+ times now and it keeps working.

I'm really at a loss to explain this behavior and welcome any advice on how to fix the issue. Please let me know if any more information is needed.

Weird. MP4 works fine here. Is it maybe only that one particular file?

I get the same behavior with AVI, MP4, MKV, WEBM; really just any video preview at all it would seem.

I have also reinstalled Windows 10 since my first post for an issue unrelated to this, but I'm still experiencing this issue. That most likely rules out any odd software/configuration causing the problem.

We will have to look at this again in the 64-bit version. All this codec stuff is deeply related to bitness.
