Are you following the instructions at Workstation Installation — Isaac Sim Documentation to run Isaac Sim on Windows? Have you execute the post_install.bat script?

Thank you, it works.
The path should be fixed, C:\isaacsim, I encounter errors since changed the path.

im still having the same problem even with the provided solutions

@bananadound maybe making a new thread would be a good idea, so you can attach any or all relevant log files for troubleshooting purposes
