When I launch Isaac Sim from the Omniverse launcher, I get the following error:

Apparently, he cublas64_11.dll fails to load when importing torch in some files of the isaac core extension. Isaac Sim starts nevertheless and I can use it to some extent, but I can’t use, for example, writers as they depend on the core module.
I’m working on a Windows 10 operating system with a RTX 3090. Here is the first line of the output of nvidia-smi:
NVIDIA-SMI 511.79 Driver Version: 511.79 CUDA Version: 11.6
I’ve got CUDA 11.6 installed, as I need it for other applications. Could there be a problem with conflicting versions? If yes, how could I resolve this?
