"Invalid development certificate found" on Mac

My GoogleFoo simply is not strong enough to find a solution.

I am a recent convert to Mac (don't judge). Using Visual Studio 20##? on my PC (C#), when I build and run, Life if great. On my newly acquired Mac-Mini, running Visual Studio 2019 for Mac (C#), when I build and run (following an uber easy code along video), I get "Invalid development certificate found".

Bottom line, I'm lost, Apple Support is no help on this issue. I am pretty confident my keyboard actuator. Any help, even it is a "Here let me Google that for you" would be greatly appreciated.

TIA

    dotnet dev-certs https --clean

    dotnet dev-certs https --trust

    It worked after I closed all web browsers and relaunched app.
