Trying to launch through the Omniverse launcher or via command line on Ubuntu 20.04 is giving this segmentation fault:

When using the launcher, it will allow you to select native or headless, but crashes after that. It appears to be the same error when running omni.isaac.sim.warmup.sh. It looks like the same error happens when trying to install the new 2022.1 beta through the launcher, since it calls post-install.sh (and warmup.sh in turn) and reverts the install after segfault. Here is the output of nvidia-smi:

I’ve had this install of Isaac working on this machine a few months ago, using the same drivers, so I’m not sure why it is failing now. Any thoughts?
