Fix Android Studio error: Missing essential plugin: org.jetbrains.android

Just update Android Studio 4.2.1, but fail to run with error of: 

Missing essential plugin: 
org.jetbrains.android 
Please reinstall Android Studio from scratch. 


Here how I fix it in my case, Android Studio 4.2.1 on Windows 10:


Search and delete "C:\Users\user\AppData\Roaming\Google\AndroidStudio4.X\disabled_plugins.txt"

There are two in my setup:
"C:\Users\user\AppData\Roaming\Google\AndroidStudio4.1\disabled_plugins.txt"
"C:\Users\user\AppData\Roaming\Google\AndroidStudio4.2\disabled_plugins.txt"

I delete both disabled_plugins.txt and re-start Android Studio.
