Building for Unity Android doesn't compile a plugin

Thanks for sharing this great work. I'm trying to compile a plugin with the unity generator for Android arm64 architecture (to be used on Oculus Quest 2).

I get no errors but there are no errors as shown below:

The process with the last line is shown here and no builds appear in the unity/build/ dir.

Do you have any ideas about what could be going wrong? Thanks in advance

Also when using hvcc command before compiling the plugin, I get this error:

PS C:\Users\Max\Desktop\to-test\noise> hvcc whitenoise.pd -n noise -g unity
  1) ←[91mError←[0m c2unity: Unicode-objects must be encoded before hashing

I'm not sure if that's a problem or how to resolve it? It still proceeds with generating and compiling for Windows x64 platform works.

Thanks!
