Unity freezes half of the time I start.

I mean literally the whole editor freezes when I click the New City button.

Hi @Hoohee! I had the same issue(s). However I was able to fix them by building to a WebGL build target. (edit: I was also using fork/PR: https://github.com/ChepChaf/Micropolis/tree/update-unity-to-2019.4.3f1)
