[Bug Report] Simulation program crashed when I change the name of task_env class.
Describe the bug
After I changed the name of the Task_Env class, when using GUI simulation, if I click on an asset within the display box and an arrow indicating displacement appears, the entire simulation program will crash.
Steps to reproduce
All the things in FactoryEnvPick and FactoryEnv are totally same. I only changed the name of FactoryEnv to FactoryEnvPick, I realize that the error is torch._C._LinAlgError: linalg.inv, and it burnt out when I was trying to click one of the assests in the environment(I would act normally when I click nothing, even moving my camera). And I also met same error when I directly copied the same part of code on Isaac Sim 4.2 to 4.5. But I guess the inherent reason are not same.

Add the criteria for which this task is considered done. If not known at issue creation time, you can add this once the issue is assigned.
- [ ] Criteria 1 Let the Simulation being activated by my customized class without the error.
Thank you for posting this. This is likely a bug, we will investigate. Could you please provide the driver you are using? Thanks.
I met the same torch._C._LinAlgError when upgrading the isaacsim from 4.2 to 4.5 with the same setting. When the error occurs, Franka appears to be in a very unusual position as shown below.
I believe this issue should be resolved in Isaac Sim 5.0. Please let us know if you are still hitting issues.
