Does anyone know what is causing this? google hasn't brought forward any solutions and I'm starting to worry that the sleepless nights are going to be for nothing if I can't fix it...

Information:

• Built in Unity 2020.1.0f1
• Uses new input system
• File is zip and includes the index.html, Build and TemplateData folder
• Build and run loads absolutely fine
• Tried clearing the cache and tried it on another device
• I've tried doing a dev build followed by a normal, normal upload still gets stuck and dev build runs fine

Hey Strodo and Feline, I had this issue as did someone else here who had reached out for assistance and I found this to be most helpful, assuming you are both using Unity 2020 :)

Switching on Decompression Fallback worked for me :)

For some reason unity 2020 seems really broken with WebGL, try making a copy of the project and opening it in 2019.4

This does work for me:

Using 2020.1.6 go to file>Project Settings>Publishing Settings>Decompression Fallback

WHOOOOOO DECOMPRESSION FALLBACK FIXED EVERYTHING YESSS
