Unity Play Stuck at 90% constantly

I am a complete beginner with Unity. Im doing a sound design degree and I decided to take one of the simple shooter game templates on Unity, expand it a bit and basically recreate all the sounds. I need to make it playable for the deadline and I have searched forums, Reddits etc to find a solution to this and still can’t get it to work.

Whenever I upload this game to Unity Play (WebGL), it freezes at 90%. I also get this message

‘Unable to load file Build/SAZ.framework.js! Check that the file exists on the remote server. (also check browser Console and Devtools Network tab to debug)’

Im using 2021.3.31f1 if that’s any help

(SAZ is the abbreviation for the game)

I’ve tried disabling fallback compression, tried all three compression modes, lowered the max texture size.
Im hoping it’s an easy fix which my beginner brain never thought of so any help would be appreciated!

sounds more like a bad webserver configuration

Don’t suppose you know any fixes?

What platform are you uploading to for WebGL?

Hi. For starters, I would suggest contacting play-support@unity.com, they might know better what’s going on. Also, does the problem persist if you try uploading, for example, a build of an empty project?
