It’s not clear to me what produced that output, but I managed to get Sim 4.5.0 running on my Ubuntu (25.04) system (RTX 5070 Ti) this morning using driver 570.133.07.
Significant issues with rendering and quite a few warnings along with a single error on start up (will create another post concerning those issues), but it did come up and is running at 119 fps.
I think it may be because you downloaded the issac sim in the wrong way. Maybe you used the omniverse launch method to download it, which seems to be deprecated.
This issue has been fixed already with the new isaac sim 5.0 available here off launcher GitHub - isaac-sim/IsaacSim: NVIDIA Isaac Sim™ is an open-source application on NVIDIA Omniverse for developing, simulating, and testing AI-driven robots in realistic virtual environments.
