Visual Studio (.NET Framework)

Do you still have the Visual Studio Installer or Visual Studio Manager still installed?

If you have it still installed and it opens up correctly, you could try removing all additional packages that are installed, and try reinstalling them again. It could have been a corruption issue relating to package extensions that you may have installed
into Visual Studio 2017 Community Edition. If that does not work, go to apps in settings, and select Visual Studio 2017 Community Edition and select repair. If that does not work, you could try going to TechNet, and asking there for help. It could be a
bug with the current version of the .NET Framework 48 or with the recent version of Visual Studio 2017 Community Edition.

If you can not find Visual Studio Installer or Visual Studio Manager, unfortunately in this situation the only thing I can think of is if you still have the installation file that you downloaded from the Visual Studio website. If you can't find that, then
I suggest that you download Visual Studio 2019 Community Edition, since the 2017 Community edition is not given for free anymore unless you have some sort of subscription. However, I suggest that you still check with TechNet before taking this step.
