Hi @The_reaper ,
Welcome to Microsoft Q&A!
Could you tell me how you encountered this situation? Which version of Visual Studio are you using?
Please update your VS to the latest version with Visual Studio Installer. And try to repair it in the Visual Studio Installer > More > Repair.
Then, run it as administrator and check it again.
If it occurs in specific project, please check if you have the ‘Microsoft.DotNet.TemplateLocator’ assembly referenced in your project or not.
And ensure the assembly version is 5.0.100.0.
If it persists, please share us more details in order to investigate it further.
Sincerely,
Anna
