Hey ,
Thank you for providing the full for the error you’re receiving. I’ve had a developer review these error and it seems that it’s an internal compiler error in emscripten. Please run “embuilder.py build struct_info” this script is in the SDK directory (For Example: C:\Program Files\Emscripten\emscripten\1.30.0). You may also want to try running “emcc --clear-cache” as well.
Looking forward to hearing back from you, thanks!
