I am using Windows and properly followed the Getting Started guide to install VS 2019, select the correct components, install the extension, installed .NET 5, and installed MGCB Editor. However, when I go in to create a new project, the MonoGame templates do now appear, even when searching with both the search bar and manually scrolling through the list.
The extension is installed, and I can even see it in the extensions folder. I installed a different extension which provides templates, and its templates appeared fine with no problems. I have also tried restarting, reinstalling VS 2019, reinstalling the extension, and repairing my VS 2019 installation with the Visual Studio installer.
I have been stuck on this for hours, and just want to start making games, so if anyone can help that would be much appreciated.
