That's really not enough information to go on. You need to fill in all of the details please. If you're not sure of some of them, then perhaps contact VRCHAT.

Just look at the logs, it says exact error and just need to take some actions to fix it:

2025.04.26 03:36:18 Error - [AVProVideo] Error: Loading failed. File not found, codec not supported, video resolution too high or insufficient system resources.

[Chris-RH]

You've not said anything about the media you are trying to play. Resolution, codec, FPS, bitrate? streaming or local? flat, 180, 360?
You've not said what version of AVPro its using.

[TheGP]

any video, version doesnt matter probably
not local

[Chris-RH]

Again, you've not given me anything to go on.
It could be that the videos have the HEVC codec, in which case you need to download the codec from the Microsoft store.
