Unity WebGL IAP Out of bounds Error

Hello,

i am running into a weird WebGL/UnityIAP Problem which i can't figure out. My game starts like normal but as soon as i start to initiliaze the payment part it crashes in my newest builds. I tried several combinations of Unity 2019.4 LTS Versions and Unity In App Purchasing Version, higher that 2.0.

Code (JavaScript):

1. exception thrown: RuntimeError: memory access out of bounds,RuntimeError: memory access out of bounds

In addition i have an error whenever i try to make an WebGL development Build. Telling me that Emscripten failed. However, i was able to "solve" that problem by running "PlayerSettings.WebGL.emscriptenArgs = "-s ERROR_ON_UNDEFINED_SYMBOLS=0";" before the build.

Code (JavaScript):

1. Failed running "C:/Program Files/Unity/Hub/Editor/2019.4.7f1/Editor/Data/PlaybackEngines/WebGLSupport\BuildTools\Emscripten_Win\python\2.7.5.3_64bit\python.exe" -E "C:/Program Files/Unity/Hub/Editor/2019.4.7f1/Editor/Data/PlaybackEngines/WebGLSupport\BuildTools\Emscripten\emcc" "

 

I have the same issue. Every app that I have UnityPurchasing (which I need just for mobile) crashes on startup when running on WebGL with an "index out of bounds" error.

Is there a way to turn off UnityPurchasing for webGL builds so I can see if that lets the game get past the crash?
