ISAAC Sim just crashes abruptly

While working on ISAAC Sim, it just crashes at random moments. No warnings or any sort of logs. I am having issues while working because I don’t even get the chance of saving my work.

I am launching the app from Omniverse in normal mode and ISAAC Sim version is 2021.2.1

Anyone facing the same error please comment below. Let me know if there is any method by which I can launch ISAAC Sim from terminal and redirect all the logs to a file.

System specs:
GPU - NVIDIA RTX 3090 (24GB)
CPU - AMD Threadripper (16 cores)
System RAM - 128 GB
