I recently updated my Android studio and when I tried opening previous projects this is the error it gave me.
The IDE failed to install some plugins.
Most probably, this happened because of a change in a serialization format. Please try again, and if the problem persists, please report it to http://jb.gg/ide/critical-startup-errors
The cause: /Users/mac/Library/Application Support/AndroidStudio4.0/firebase/lib/failureaccess-1.0.1.jar (No such file or directory)
The IDE also gives off these errors

What does this mean and how do I resolve it?
Worst case, how do I downgrade back to what it was before?
