This is the full log that appears when you run Isaac Sim from the folder where it was downloaded. The last line says segmentation fault (core dumped) |

Here are my current computer specifications.

When I try to run IsaacCIM after installing it, I get a segmentation fault (core dumped) error and the GUI crashes.
The same issue occurs with both versions 4.5 and 5.0. Does anyone know how to fix this?
I need help.
