Causing whole Android Studio to do nothing like a useless program and causing freezing when trying to open settings

If the current behavior is a bug, please provide the steps to reproduce.
Install both DockDockBuild and Makefile support plugins https://plugins.jetbrains.com/plugin/9333-makefile-support (Some time Android Studio ask to install DockDockBuild and Makefile when you open .mk file)
restart Android Studio
Open any Android projects

What is the expected behavior?
Let Android Studio run fine

Please provide all relevant details.
There is an issue reported on Makefile page kropp/intellij-makefile#191
Either DockDockBuild or makefile should at least handle this conflict with a warning because i'm sure some users have both Makefile support and DockDockBuild installed even they don't know and they will get stuck with this issue for too long time
It had took me an hour to help my friend solve this problem with Android Studio

To fix it:
There is an error on the down-right corner. Click on it and disable Makefile plugin and restart

Now you can either disable or uninstall Makefile support or DockDockBuild
