Visual Studio 2013 stopped working after removing dlls from GAC

After removing some dlls from the GAC using gacutil -u <dll> in the Visual Studio 2013 command line, my Visual Studio 2013 has stopped working.

When I open it, it crashes with the following error in event viewer:

Faulting application name: devenv.exe, version: 12.0.31101.0, time stamp: 0x54548724
