    Resolution Note (fix version 2022.1):

    The underlying issue has been fixed in Unity 2021.2 and beyond with the new Emscripten toolchain. Unfortunately it's not possible to fix this instability for older versions of Unity on Windows. Please use Linux or macOS as a workaround for older Unity versions.

    Fixed in 2022.2.0a2
