Hi,
We are experiencing il2cppcore error when Building Android Build using UNITY. The error is not persistent and rather occur randomly i.e Sometimes the build fails but sometimes it is successful. We are still trying to get to the bottom of the cause and steps that result in 100% reproduction of the error. One theory is that when a build is created with some GIT changes the build succeeds for the 1st time but it always fails in subsequent attempts. Please find the Error and other detail below.
