I have a very similar issue right now, when using HereSphere (full app) on my Quest 3 , if I navigate to my XBVR server address, then click the Heresphere API icon, a scene processing counter will count to about 1300/8000 videos before crashing to the Quest desktop. I haven't gone through my crash logs yet but I'm assuming it's a memory limitation issue?
Is the only solution to manually migrate my data and settings to a newly created XBVR instance? Do I also have to manually iterate through the entire library with a smaller number of videos each time? Just wondering if these are the only solutions at the moment.
