Monodevelop can't open files from project in github repo

Monodevelop won’t open any files that belong to projects in my github repo folder. I tried both copying and pasting a project in and creating a project directly in the folder; in both cases, I can open and run the project, I can even build the project, but when I try to open any of my script files using monodevelop, I get the following error message:

System.FormatException: String was not recognized as a valid Boolean.
   at System.Boolean.Parse(String value)
   [...]

Sometimes the error message also has this heading:

Error while updating status of command: 
   MonoDevelop.VersionControl.Git.Commands.SwitchToBranch.

I also just found that when I open the Version Control menu in Monodevelop in any project (even outside a github repo), a bunch of error messages (similar to above) come up in a row, and then Monodevelop crashes. Does anyone know what this means? Thanks!

Yes! I finally found someone who had the same problem as me:

His solution worked for me also (Disable Git support in Monodevelop via Tools > Add-in Manager > Version Control > Git Support > disable).

Did you try to “Sync MonoDevelop Project” in the “Assets” menu?
