If you have downloaded a Unity Standalone game folder, and the game crashes or has problems, you might need to check the Standalone .exe logs.
They are in the following folders:

macOS ~/Library/Logs/Company Name/Product Name/Player.log Windows C:\Users\username\AppData\LocalLow\CompanyName\ProductName\Player.log Windows with Backslashes C:/Users/username/AppData/LocalLow/CompanyName/ProductName/Player.log Linux ~/.config/unity3d/CompanyName/ProductName/Player.log
Check the above folders for your operating system and check out the log!
