I’m using Unity 2019.3.9f1, and my build settings are as follows:
When I start a build, it gets to about 90% before failing, with 3 errors logged in the console:
Here is the full stacktrace for each of these errors:
--- ERROR 1 ---

I have no clue how to proceed from here, and Googling has given me a lot of similar looking errors that are different enough to not apply to me (or, at least, the fixes that worked for their problems didn’t work for me). I do have WebGL module added and installed for this version of unity.
Anyone know how to fix this build issue?
