Are you using the latest build of the GDExtension? Unfortunately I have an arm injury making it painful to use my pc, I’ll have a look at this problem tomorrow to see if there’s a mistake in the building process.
Okay, so I had a look at the code and I realized that we have no Windows ARM build yet. The lines do exist inside of the gozen.gdextension file, but the actual code for compiling for Windows ARM is something I haven’t worked on yet. This is where the mistake was happening, one of the paths for the library files was wrongly pointing to the Windows arm folder instead of the x86_64 folder. I’ll be creating a quick fix for this which will go live in the next couple of hours, thanks for reporting it! ^^
