I had this same issue yesterday. I'm on Windows/DeoVR/Vive SteamVR. I watched a bunch of videos with script (maybe 30?) then all of a sudden all other videos stopped working. The ones I'd already watched still worked though. Essentially videos had the script icon in the thumbnail, but did not have the heatmap or script icon in the player once I clicked into it and played.
I tried a couple of of things, but none of them worked.
- uninstalling/reinstalling DeoVR
- clearing cache on exit and re-signing in
I tried signing in to SLR in Chrome then clicking the "play in DeoVR" button in the player, which then launched the video in DeoVR and scripts worked in this case, for the very same video that didn't work playing directly from the DeoVR interface. After doing this, playing the same video by opening from the DeoVR interface didn't show the script icon.
It looked to me like the links being served via the DeoVR format somehow had scripts disabled but the links for the same videos deeplinked from the web were fine.
