Can Unity clean the WebGL / IL2CPP code cache between editor versions? Seems like it’s a recurrent issue due to the fact that the compiler backend keeps changing.

"RangeError: Maximum call stack size exceeded" after Unity has loaded in WebGL.

Hi, I’m currently trying to solve above problem in our educational game project and I have come to a dead end with searching solutions all around internet. Our team is trying to integrate Unity game in to our own system built and coded with Vaadin, Java and Javascript. The thing is that our game needs to take parameters as “setups” from our system and use them in the game and when game is done, send something back with callback function.

An alternative workaround to Clean Build is to delete the BuildCache and Bee folders in Library prior to a build - maybe that’s the same as Clean Build.

Other than that I’m quite happy with the alpha and looking forward to this being fixed.

My understanding is that it is indeed the same.

We currently have a PR in review that seeks to implement this behavior. Once it lands in 2022.1, the plan is to backport it to 2021.2 as well.
