Recently this has happened several times in DeoVR Hyper on my Pico 4 Ultra:
1: Started browsing videos, everything is dandy. Checking out several one after another without issues
2: After a while, opening a video seems to be stuck loading forever. Only black screen in VR. Play/pause in media control does not do anything
3: Now it's not able to load any video. Have to exit DeoVR Hyper and open again go be able to load videos.
That videos don't load is a old problem. I've seen it both in DeoVR and DeoVR Hyper, on both Meta Quest 2, Quest 3 and Pico 4 Ultra. Before that has only been temporary. When exiting the video and opening it again a minute later it has worked fine.
Lately the app is not able to recover. Today I got a new software update to DeoVR Hyper, but saw the same thing after update.
