Describe the bug
Hurray to IsaacLab 2.0!
When the first user installed Isaac sim, either binary or pip install the OmniHub can be launched correctly,
When the second user install Isaac sim, again, binary or pip, will not be able to launch OmniHub when isaac-sim is launched, and shows error message
OmniHub: ThreadId(03) Hub encountered error. Trying to reconnect to Hub. retry_reason="Hub failed to launch: Io(\"child exited with exit status: 101 without writing file
It took me a while to find out the solution is to change the cache path in the account where the omniHub is correctly launched, clicking the CACHE:ON on the top right side of the IsaacSim GUI, Then Change the Cache Path to correct user.
That is also saying, under one system, only one user can be able to use OmniHub, I realize this is issue of isaac sim not isaac lab, I want to post here and so people ran into same issue can find the tricky but easy solution!

Following up on this, it seems that the when running multiple instances of Hub, the cache directory should be different for each instance. You may be able to work with the env variables that Hub works with, specifically OMNICLIENT_HUB_CACHE_DIR. See this doc for reference.
