Same issue here, entire client site down. Had to manually deactivate Google Analytics For WordPress plugin to restore site.
We need a bug fix ASAP so that no analytics are lost! Also, MonsterInsights needs to do a better job testing to catch these sort of conflicts before widely releasing updates.
I’m sure it’s common for Auto Updates to be enabled these days, which means in a case like this, a site can go down and you don’t even know.
