    I had this problem in 2021.3.8 and the problem was solved when I unchecked the Development build. For some reason that did not want to build.

    This issue still exists for me in 2022.1.x and 2021.3.1 (LTS).
    I am getting issue when trying to build photon for WebGl.

    Library\Bee\artifacts\WebGL\build\debug_WebGL_wasm\build.js: undefined symbol: devices (referenced by top-level compiled C/C++ code)
    UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

    This was also reproducible for me when using .jslib files.
