Hi everyone!
Theres seems to be an issue with the AyonUsdResolver Binary for Maya2026 (tested in Maya2026.3):
The AyonUsdResolver Plugin fails to load with USD v25.05 with the error:
Error in 'pxrInternal_v0_25_5__pxrReserved__::PlugPlugin::_Load' at line 244 in file D:\Jenkins\workspace\EMS\ECG\ecg-usd-build\full\windows-release\ecg-usd-build\usd\pxr\base\plug\plugin.cpp : 'Failed to load plugin 'ayonUsdResolver': Die angegebene Prozedur wurde nicht gefunden.
in 'C:/Users/{USERNAME}/AppData/Local/Ynput/AYON/addons/usd_0.1.4/ayon_usd/downloads/Maya2026_Py311_Win_Windows_AMD64/ayonUsdResolver/lib/ayonUsdResolver.dll''
However, with USD v24.11 the plugin loads without errors. But, as stated in the AYON Maya OpenUSD Workflow the resolver fails to resolve the entity URIs.
Below a summary of the log (I deleted some lines) where you can see that the binarys are initilized correctly at startup.
(Don´t mind the Rez Launching - I also tested it without Rez, with just a clean vanilla Maya 2026.3 install and it gives me the exact same error.)

I also tested the Resolver in In Maya 2024 and Houdini 21.0.x (both launched with Rez) the resolver worked perfectly fine there.
So, the question now: Is there indeed an issue with the binary, or did I forget something to make it work in Maya 2026.3?
Cheers!
