media files no longer playing in 4.11 standalone

Hello,
In 4.10 all my video textures were playing fine in both the viewport and standalone game.
Now in 4.11 they still work in the viewport but in standalone not only do they not work they also make whichever actor blueprint they are applied to totally disappear. I have one on just a static mesh and it appears black.
The video files are on a regular static mesh and also in actor blueprints they are variables that start playing on overlap events.

They are .wmv files. I have tried both local and relative paths (i.e. ./Movies/colorField.wmv and C:/UnrealGame/Content?Movies?colorField.wmv) I deleted them and re-imported, restarted, updated video card drivers. Always getting the same thing.

One strange bug - when I click on the yellow reset arrow next to the file path in the asset viewer for the imported media file, I get an immediate crash that gives me no information on the crash report.

I tried a blank level with no starter content, added the videos. They work in the viewport and checkered pattern in standalone. I did the same thing with the same video in 4.10 and it worked fine in both viewport and standalone.

Any ideas? Thanks for any help!

thanks for the reply! - one other bug I noticed is the sound from the video that I turned into a sound cue…it just plays the first like tick of the sound again and again so I get a static sound instead of the video - this is in viewport and standalone.

Hi, Just reporting that a few random clients would have the video playback normaly, something like one or two out of 8 clients, the rest get a black image.
Any status on hotfix or similar?
Best Regards

This was reported as fixed for 4.11.2, so you should not be experiencing the issue still. I am assisting a user here where he mentions the fix for him is to run the executable as the administrator.

Try this out to see if it resolves your issue as well.

Cheers,
