This works absolutely fine when "Specflow for Visual Studio 2017" extension is removed from Visual studio

Steps to Reproduce

Create a Specflow/Easy repro project
Open the solution on Visual Studio 2017 Enterprise edition
Install the "Specflow for Visual Studio 2017" extension
Check out a git branch
Try switching to a new git branch
Visual studio crashes and needs to be restarted

Did you switch the branch in Visual Studio or with another program?

Could you please also check if there is any error logged in the Visual Studio log file (%APPDATA%\Microsoft\VisualStudio<Version>\ActivityLog.xml)? Or are there any details about the crash in the windows event log?

Inside Visual Studio, it happened again just now. Trying to look for the Activity log now
