Visual Studio 2015 Pro Update 3 never launches. After sometimes, it turns into not responding and I have to close it from task manager.

Hi @Kottayi, Suraj ,
Welcome to Microsoft Q&A!
Please try to run your VS in safe mode: open Command Prompt and go to C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE folder, run the command: devenv /Safemode to run vs without any third-party VSPackages, check if it launches normally or not.
Besides, you can try to repair your VS2015 by opening your Control Panel > Uninstall or change a program > search it > right-click on “Change”. Before repairing, I suggest you check for updates and install all pending Windows updates.
Sincerely,
Anna

It runs fine in safe mode.
However when I try to run my soln I get "Unrecognized Guid format" error.
Even the repair option does not help. VS 2015 pro still doesn't launch normally
If it runs fine in safe mode, it may be caused by installed third-party extensions. Please go to Tools > Extensions and Updates > Installed > disable or uninstall all installed extensions. Then, run your VS as administrator and check again.
Besides, please try to create a new project and verify if the "Unrecognized Guid format" error disappears.
