Hi @antopilo, we have seen similar issues in the past, usually related to environment variables. a couple of things to check here:

Check to make sure your python and system Paths aren't conflicting with mayausd. you shouldn't have anything usd on your PATH & PYTHONPATH at system level, as Maya sets all of the necessary env vars at the session start.

If that doesn't solve the problem, I would recommend double checking your mayausd.mod file (you can find this file under "C:\Program Files\Common Files\Autodesk Shared\Modules\Maya\2024"). All of the paths should point to a common root directory, that being the installed location of mayausd.

Hope it helps! :)

If you encounter a similar problem in the future, my issue was primarily caused by the PATH environment variable. It included a path to some USD libraries that were present alongside the libraries installed with the plugins. Once I removed these paths from the PATH environment variable, the plugin loaded without any issues. Therefore, it's important to eliminate any paths related to USD libraries that are not part of the libraries the plugin is attempting to use. Generally, the relevant libraries for the plugin are located in the installation directory, typically under C:/Program Files/Autodesk/MayaUSD.
