Visual Studio 2022 run without debugging button greyed out

Question

For some reason, whenever I try and run my project in visual studio 2022, the "run without debugging" button is greyed out, I have tried to find multiple answers to this problem but it seems like an uncommon error, it is my only project in my only solution folder, so I'm not so sure what could be causing it.

In case it helps, I'm trying to run a monogame template project and I'm not signed in

here is an image of what my UI looks like:

I just faced this right now, but for me the reason was:

I had opened the program.cs file instead of .sln file. The problem simply solved when I closed the instance and double clicked .sln to open it!
