WebGL Build throws returns runtime errors when ran in native multi-thread mode
Reproduction steps:
- Open the attached project
- Switch the Target Platform to WebGL (File > Build Settings > WebGL > Switch Platform)
- Build And Run the project
- Observe the Errors in the Browser’s developer console (F12)
Expected result: The WebGL Build doesn’t produce any errors and runs smoothly
Actual result: The WebGL Build throws a lot of errors and doesn’t run
Reproducible with: 2022.2.0b9, 2023.1.0a12
Could not test with: 2020.3.40f1, 2021.3.11f1, 2022.1.18f1 (Couldn’t build due to WebGL Build errors)
Reproducible on: Windows 10 (21H2)
Note: If the browser throws a “Your browser does not support multi-threading” error, run the build using the attached emrun.py python script from the build folder using the command line/terminal with the “python emrun.py index.html --no_browser --port 8000” command
