Failed to load Isaac Sim

Hi All,

I have problems starting up Isaac Sim. It did start before on Ubuntu 22.04. But after some restarts now it does not want to load.

I started Isaac Sim with the launcher and added the extra args -v -vv. It gets stuck on following line:

Thanks for the help!

Hello,

I solved the issue by unloading an extensions that I loaded in.
