"Unsupported" Error on opening Visual Studio

Unreal noob here. I made a new project last night and installed Visual Studio, and today I tried opening my project in Visual Studio only to be met with this error:

When I click “OK” it opens a “Migration Report” in Chrome that has this message: “The application which this project type is based on was not found.”
I’ve looked around on Google and found a couple solutions such as making sure my environment variables are configured properly, restarting my computer, and deleting my ProjectFiles directory, all to no avail.

How do I resolve this issue?

For referece, here is the information related to my Visual Studio installation:

Hey Chuckleluck-

Was the project created before you installed Visual Studio onto your machine? If so you may want to try creating a new porject? Also, was the project you created a blueprints project or a C++ project? By default blueprint based projects do not have the code necessary to open in Visual Studio unless you use File->Add Code to Project from inside the editor.

Cheers

My main project was created before I installed Visual Studio, and I added code via File > Add Code to Project. However, I’ve also tried creating a new C++ project after I installed Visual Studio, and the problem persists.

Hey Chuckleluck-

After deleting the ProjectFiles folder you would need to right click on the .uproject file and select “GenerateProjectFiles.” If you are still having problems you may need to uninstall both Visual Studio and the engine. Then reinstall both, making sure to install Visual Studio first.
