Cannot enable addon on Windows 10

[dreisicht]

I downloaded BlenderUSDHydraAddon_1.0.21_Windows.zip, installed with the Blender add-on UI, and I get the following error:

2021-09-22 10:57:11,539 INFO hdusd.init [16336]:  Loading USD Hydra addon version=(1, 0, 21), build=b0bf57e

What blender version is this?

[dreisicht]

It's 2.93.4!

Looks like from pxr import UsdGeom tries to load pxr library from C:\Users\peter\Documents\pixar\lib\python\pxr. Addon has its own pxr library inside C:\Users\peter\AppData\Roaming\Blender Foundation\Blender\2.93\scripts\addons\hdusd\libs\usd\python\pxr, such library should be used. Try to remove C:\Users\peter\Documents\pixar\lib\python from PYTHONPATH if it is there.

Looks like that resolved one issue. Now I run into the following one:

2021-09-29 14:28:01,949 INFO hdusd.init [20824]:  Loading USD Hydra addon version=(1, 0, 21), build=b0bf57e
Fatal Python error: take_gil: NULL tstate

I think my python installation is a bit off, so feel free to close the ticket in case you don't want to invest time into debugging this.

Not actual anymore.
