    Tested on 2022.2.0b16 and still occurs! A fix would be highly appreciated. Being able to profile our webgl client is very important.

    This is really frustrating not having profiling work. My app seems to be super slow on Chrome but not on Firefox - and not being able to profile it to figure out what's wrong is making me consider using a different game engine...

    Can't believe that it has been reported half a year ago and this is still not fixed. :(

    Impossible to profile any WebGL stuff in 2021 LTS, and it gets tagged as low pain issue?

    We're also running into this issue after upgrading to 2021.3.1f1. Unable to profile our WebGL application using "Build and Run" with "Development Build" and "Autoconnect Profiler" switched on.

    Would be really helpful to have a fix or workaround for this.

    Again, this is not just about the Test Runner in 2022 - this is about the WebGL profiler in LTS 2021.
    Profiler data sent to the Editor is corrupted, so it's impossible to profile our games.
