Additional information about the issue reported

I believe this was caused by the upgrade of all of arcade-services to use .net 6. The latest version of darc requires a 6.0 runtime to be installed in the machine.

5.0 goes out of public support this month, so I’d also expect it to disappear from the 1ES images soon.

I would also suggest figuring out how the other dotnet versions are already installed on the images we use and look into if a) they even should be and b) if they should be, why 6.0 isn’t also installed… and then make sure that it is.
