Many errors are displayed when starting the Isaac Sim 4.2.
Below are some error of them.
[Error] [omni.ext._impl._internal] Failed to import python module omni.isaac.core from

Environment:
Windows11Pro(RAM68GB/JapaneseOS)/RTX4500(538.15) VRAM20GB
*By using IsaacSimCompatibilityChecker : All Green
Same thing happening to me with a HP workstation with RTX3060 12GB VRAM, on windows 11 PRO with 64GB RAM. CompatibilityChecker: all green.
In the same machines Isaac Sim 4.1 is running just fine.
To add some info: the same problem happens in my laptop, Dell G16 with RTX 4070 8GB VRAM, windows 11 PRO and 32 GB RAM. Here the compatibility check is orange on VRAM.
I could find I way to get it working in ubuntu, and there Isaac SIM 4.2 seems to work great, even more FPS than on windows.
In both my computers on Windows Isaac Sim 4.2 starts with these many errors, but do start. The menus then are almost empty, most functions are absent, so it’s not really usable.
These many (many!) errors seem all about it not being able to load some packages that are in fact where is he’s looking them, so not sure what to try to solve…
