For some reason, the game crashes and freezes after I go through to door after collecting the key for the hidden room with the red cord puzzle, and then I get to part with the water sounds. It just freezes and then the game crashes???
I used 2020.2.6f1 (so that Universal Render Pipeline would have screen space ambient occlusion) which is a full version of Unity, but it isn't an LTS (long term support version). For my next project I plan to use the 2019 LTS + High Definition Render Pipeline for better stability and higher graphical fidelity, but I can't build it for WebGL if I use that.
