Videos not working "Error: WindowsMediaFoundation received empty file"

I’m relatively new to Unity and I’m having a problem with videos.

Whenever I put videos in Unity everything works and when I build it everything works. But when I send the build to others, the video files don’t load.

Error: WindowsMediaFoundation received empty file C:/users/_____/Download/klapp du stück-20231003T195213Z-001/kalpp du stück/Mia_s Sketchbook_Data/sharedassets0.ressource

How can I fix this?

I’ve solved it two different ways. Before Unity 2023 I needed to add “file:///” to the URL I was loading from. However now in Unity 2023 I can drop the file prefix, but the load location has changed. Before I would load with …/mediafolder/video.mp4, but now I need to load from an extra folder up @ …/…/mediafolder/video.mp4
