SQL Server Management Studio 18 is not opening just a splash screen pops up.
SSMS 18 is worked for few days (4-5) and from today just a splash screen pops up.
This is a duplicate of https://feedback.azure.com/forums/908035/suggestions/37502512, as Glenn said.
The issue was fixed in SSMS 18.1.
The solution is to overlay Microsoft.VisualStudio.Shell.Interop.8.0.dll in C:\Program Files (x86)\Microsoft SQL Server Management Studio 18\Common7\IDE\PublicAssemblies with the copy from ..\PrivateAssemblies\Interop
