Hello guys, i share a fix for that issue here: I hope Unity will be update soon for definitively correct this issue !!
Hello, This seem to be an issue with unity & catalina. https://steamcommunity.com/app/220200/discussions/0/1609400247629200531/ I find a fix who work fine for me: Search for the executable file, right click on it, and select "get info". Then just check "open in low resolution". The game will open in the resolution of your desktop but will work fine in full screen !!
