Build errors on WebGL Builds in 2021.2.0a8 - a9

Per recommendation reposting from this thread :

Because of the Safari-Camera access only added in the alpha branch of the 2021 Unity, I’m currently using alpha.

I’m build errors relating to Editor, IPreprocessBuildWithReport.

Sample project can be found here https://github.com/Bersaelor/Unity2021AlphaBuiltToolTest a or on https://fogbugz.unity3d.com/default.asp?1322929_hpke3k244l3q24c1 .

Thanks a lot for submitting the bug report @Bersaelor .

The issue should be fixed as of a10:
