Arnold Shader network missing in Houdini 17.0.352

Hello,

I am having an issue with missing Arnold Shader Nerworks. We are running HoudiniFx build 17.0.352 on Windows 10 in the Computer Lab at Uni (Education License). The main problem is every time we open a .hip file the menu and nodes inside the Arnold Shader Networks that were previously created are missing. The only way we could make it work is to create a new file and then open our .hip file from the new one and everything will work as expected. Attached are some pictures illustrating the problem. We already contacted our IT technician to check everything is ok with the .env file and to make sure we are running the latest version of the Arnold plug in, which we are, but still could not figure out what is the issue.

Anyone that might know what the issue could be?

Previously created with what version of HtoA?

There's no errors when you load the old scenes?

If you start Houdini and don't open any scene, are the shaders missing?

Missing shaders is often a symptom of a problem with the HOUDINI environment eg setting HOUDINI_OTLSCAN_PATH for some other plugin

No, shaders work fine when launching Houdini 17

Hope this can be useful for a diagnostic. Thanks!
