Problem with material adding/editing

Omniverse Isaac Sim
,
1

I am having problems with adding materials to scene, or editing an existing one.

scenario 1.
Isaac Sim loads, empty stage opens.
When I try to add OmniPBR or OmniGlass material to the stage the application freezes, and stage tab looks like:

Isaac Sim does not crash the app stays in frozen state forever.

scenario 2.
I open a *.usd file, that I’ve been working on Isaac Sim, and there are materials (in the stage) that were taken from blender. When I click any one of them, the app freezes. (before the property tab loads)

scenario 3.
Isaac Sim loads, empty stage opens.
I add a Cube to the stage, and then add OmniPBR, nothing goes wrong, I can edit the material, change its color etc.

I didn’t find anything wrong in log files, there are no any crashreports when this happens. But I can share the log files, or any other extra information if you need.

Yes, under the title “Material Properties”, first step “1. Click Create → Materials → OmniPBR twice.” The app froze just after adding a OmniPBR material.

I’ve waited approximately 12 minutes but nothing changed.
The following is the last line of the log file from “/home/‘USERNAME’/.nvidia-omniverse/logs/Kit/Isaac-Sim/4.2”

2024-10-24 04:32:31 [418,833ms] [Info] [rtx.neuraylib.plugin] [EntityResolver] DONE ::OmniPBR <—> ::OmniPBR (file:/home/‘USERNAME’/.local/share/ov/pkg/isaac-sim-4.2.0/kit/mdl/core/Base/OmniPBR.mdl)

Update:
The issue does not exist on Isaac Sim Version 4.1.0.

Does this freezing issue occur when you attempt to create a second OmniPBR material? Specifically, does it happen when you click Create → Materials → OmniPBR for the second time to create ‘OmniPBR_01’?

I cannot reproduce this issue on my end using Isaac Sim 4.2.0.

me too, my isaacSim is also Stucking, when I add OmniSurface material, just freeze. V4.2
