Android build error

I’ve recently installed Windows 7 on my computer and I am trying to package a game to my android device. When I launch this is the error I get.

LogPlayLevel: Program.Main:

ERROR: AutomationTool terminated with exception: System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.

Followed by
LogPlayLevel: BUILD FAILED

PackagingResults:Error: Error Launch failed! Unknown Error

Never mind. I fixed it by turning off arm64 support.
