NOTE: I had to install nvidia-driver-570-open for the card to work at all, and I use a chip with amd64 architecture.
Isaac loads but freezes most of the time I try to launch examples, and on top of that many files/folders mentioned in the documentation simply do not exist on my machine.
Detailed Description
The simulation loads, but as soon as I try and load a robot, it freezes. I can create basic things such as a ground plane and prims without crashing (at least, in my limited experience), but as soon as I try complex examples, or even looking into physics properties of the robot in the second quickstart tutorial (https://docs.isaacsim.omniverse.nvidia.com/4.5.0/introduction/quickstart_isaacsim_robot.html), IsaacSim freezes.
I have read on forums that the Blackwell architecture is not currently supported, so that might be it - but then agian maybe it is not. There is probably little to do until my RTX is supported, but I still find it weird that IsaacSim should freeze even at the quickstart tutorial…
Another concern is that I cannot even follow the documentation as several folders seem to be missing from my install (e.g., standalone_examples). For information, I used the pip install with a conda environment by following the instructions provided here: Python Environment Installation — Isaac Sim Documentation
While eagerly awaiting an update that will allow RTX cards with Blackwell architecture to be used with IsaacSim, I would be grateful is anyone could at least 1) let me know that either there is something wrong with my install, or the documentation is incorrect regarding files and file paths; 2) confirm that the freezing issues encountered with the provided examples will be solved by the update.
Many thanks in advance for your time.

Additional Context
I need some form of confirmation that the pip installation is supposed to be correctly working.
I assume this implies the instructions mentioned in Quickstart with Isaac Sim — Isaac Sim Documentation work on your setup. Could you provide the full log for the issue from the second Quickstart instructions on your workstation setup?
The first quickstart tutorial with the prims works indeed. I can also load stages and add prims (at least, as far as I can tell). The freezing issue seems to arise with robots.
I attach the log obtained with the workstation installation.
I’m not sure if the following log snippet is related to the issue, but you may want to check or explain why omni::anim::navigation::INavigation v3.2 is in your system.

The Ubuntu install is fresh from last week, I haven’t installed much besides IsaacSim and Nvidia drivers. As far as I can tell, this must have been installed through either the pip install or the workstation install.
Your question makes it seem like it shouldn’t be here, so… should I try and remove this? If so, how?
I can try, of course, but I strongly suspect that it won’t matter as long as I don’t clean up whatever has been put in place by the pip install method. Do you have any suggestion how to wipe the slate clean, short of a fresh Ubuntu install (which I would like to avoid as I have been installing a few other things - successfully, I must say, as IsaacSim is the only issue)?
Reporting on corrective actions.
I did two things:
from the previously created conda environment:
pip uninstall isaacsim[all]
rm -rf ~/.local/share/ov
I can now report that the physics inspector does not crash any longer. I will keep pushing through the various tutorials to see if everything works as intended.
My conclusion so far is that the workstation installation is the way to go at this stage of the 4.5 development lifecycle (especially considering that the documentation seems to be written for this approach), and that the pip installation should probably be considered broken and not usable.
