    Hi

    I'm working on a project for WebGL platform and have been exporting previous builds with no problem
    Suddenly it's not working anymore and all VS functions don't do anything on the exported build
    There's no problem while running in the editor though and no error in the console or anywhere
    I've been trying to sort this out for the last three days and still have no idea what's going on
    Also tried to disable the VS gameobject and cut all connections but same error in the browser console
    If someone has an idea that would be great to know thanks
    Unity 2021.1 / VS 1.5.2

    Still been stuck for a week, could I get some help please?
    I used Bolt VS for more than a year and never got this export problem
    Works fine in editor and Desktop export, so is it a bug in Visual Scripting/Webgl ?

    Hi,

    With this log message it's pretty hard to really know what your problem is.
    First, for the warning "System.MethodAccessException: Attempt to access method 'System.IDisposable.Dispose' on type 'emsc.emsc' failed." do you have some sort of reflection code trying to access this emsc.Dispose() method? It looks like you can't do that.

    Then for the error about the deserialization, besides the null exception error unfortunately I can't really know what's going with just this log. As it looks like it appears on WebGl build only, this is probably an IL2CPP issue. Did you try to deactivate code stripping to see what's going on?

    Thanks for the reply
    I actually ended up disassembling the whole project to find the problem
    Apparently wasn't directly a VS problem, but with a plugin (Paint in 3d)
    That plugin seems to crash in a specific condition in WebGL
    And I'm also referencing some methods of the plugin in VS
    So maybe that's why VS also showed up in the errors
    I wish the error log would mention the plugin script or something
