I'm having the same problem. The only workaround I've managed to find is to make a "development build" and upload that one.
what do you mean by "development build"? like in build settings in unity or something in itch.io (this is my first game so i really want it to work)
This is what I've done to get my game to work. Note this is not a fix just a workaround I've found to make my WebGL work in itch.io
Not everyone is having this problem and this is not the right way to release a game in any way. But for testing purposes it seems ok!
thx so much! i look foward to making more itch.io games!
