dotnet watch run FileNotFoundException (System.Runtime 7.0)

After updating Visual Studio, which installed the .NET 7.0 SDK, I can no longer use dotnet watch run on my project. I have made no other changes (all target frameworks are still 6.0). dotnet run works just fine, but when I use dotnet watch run the solution builds and then fails with the following exception: 
dotnet watch 🚀 Started

I was expecting that the update alone wouldn't break anything, at least until I updated my project(s)... I can't find anything on Google except for creating a global.json file or possibly changing the target framework, which I do not yet want to do because I want to stick with LTS for this project.

@calledude Reinstalled how? I just went to microsoft and installed .net 6.0 SDK, but still nothing. However the error says it's looking for System.Runtime version 7, which I believe the dotnet watch command is trying to use based on the error message, and not the actual run command...
