Esoteric Ebb: Fatal error failed to load il2cpp. To fix this error try the steps below.
Disable Windows "Smart App Control"
Windows has a deep security feature called Smart App Control that sits above your standard antivirus. If it's set to "Evaluation" or "On," it can completely block Unity's IL2CPP binaries from executing without ever showing you a standard popup or quarantine log.
Press the Windows Key and type Smart App Control.
Click on Smart App Control settings.
If it is turned on, switch it to Off.
