Please provide the complete log and try if the issue persists with a single display.

Thank you for your reply, but the above is the complete error log in crash*.txt. he error log path is ~/.local/share/ov/data/Kit/Isaac-Sim Full/4.5. The last error row in terminal is segmentation fault. The isaacsim still crash with a single play.

@cometq i could be wrong, but maybe the mod is looking for the latest kit log, which you should be able to locate in the following directory:

~/.nvidia-omniverse/logs/Kit/Isaac-Sim Full/4.5/

7

Yes, could you also provide the latest kit log.

Also, have you tried the recommended driver versions, e.g. 535.129.03 or 570.133.07?
