The application freezes as soon as play the simulation

I have created this design and loaded in Issac sim. After loading when i clicked on play button the app freezes, and unable to access other options to move joints. I tried to limit the fps to 90 also initially it was around 400.
You can see the gpu usage before and after loading the design.
