Hey!
I have a serious issue with 4.5. I’m setting up a scene with some conveyors and people walking around and everything works great. I then added some new assets from SimReady and when trying to start the simulation again, IsaacSim completely freezes.
The scene was not saved, so I restarted isaacSim, opened the scene without the new assets and it still freezes.
I had the same issue yesterday, which I could only resolve by ‘reinstalling’ 4.5 (unzipping, removing all caches) and recreating my scene, which took me quite some time.
What do you need in a full bug report? This currently blocks my development completely.
