Updating from v1.2 to v1.3 or v1.4 causes an error in building the WebGL version

Updating from v1.2 to v1.3 or v1.4 causes this error in WebGL builds. The version of Unity I’m using for the build is 2020.1.5f1.

Builds for other platforms are building fine. It was building fine before the update. Is there any solution to this problem?

If I updated to v1.5 and removed the customParameters: '-nograhpics' , I was able to build it without any errors. Thank you.

@webbertakken In my sample repo which is using v1.2 I’ve created a new commit that leads to a segmentation fault. After reverting that commit, it worked again, as you can see here:

Commit artikel3 introduces a seg fault, when reverting its gone and comes back, if you revert the revert again.

However, building locally on macOS works as expected.

I have not investigated it further, but it looks like its a combination of the builder and code.

Thats the commit introducing the seg fault: https://github.com/BoundfoxStudios/windows-developer-unity/commit/2aa20ca5c02b6b70721827e0eb13392a70bed963 unfortunately, a bigger one. 😃
