Unity 2020 WebGL freezing at 90%?

Hopefully, you have found this article before too much hair pulling and head banging from trying older solutions to very similar problems listed online.

Problem: You have built a game with Unity and now are ready to share if with your friends and family.. But when you upload the game to your favorite game sharing service and test it, it freezes during the load.

Reason: IF your game sharing site has you upload your game as a compressed file (ie. a Zip file), their systems decompression system may be messing with the built in system used by Unity as a default.

Solution: The easy solution is to disable Unity’s Compression Format settings in the Player settings. If this does not work or it still take a long time to load, you may want to take a look at the resolution sizes of the artwork used in your game.
