Game freezes on HTML5 build

Thank you very much for your answers! I will try to answer them all and my discoveries so far:

I’m using firefox and . The camera seems quite normal on the mobile preview (except for maybe a texture or two). A friend of mine tried the project and it works for him, minus the colors. The controls are working for him but not when I package it. When I installed emscripten, Unreal could not open any project and crashed every time I tried. After restarting my computer, it worked however. This might be the reason it bugs out. I tried replicating it (uninstalling and reinstalling emscripten) and I get the error again. Here is the start of the error message, I can’t link the whole of it because of the character restriction:

Access violation - code c0000005 (first/second not available)

Assertion failed: ::GetEnvironmentVariable(TEXT(‘PATH’), PathVariable.GetData(), PathVariable.Num()) == PathVariable.Num() - 1

This is how the DefaultSprite looks like. It’s not really working as it is right now so any pointers on how to solve it would be awesome
