Transactionmode set to classes is different than the one set to Addin Manager

I had that problem in the past, but usually a reboot helped me to get it fixed. But lately, probably since I am using a new computer, even that stopped working (or I am not patient enough to try it often enough :)).
When I am trying to load a dll in Revit 23 into Addin Manager (v1.5.6), I am getting the error message

The TransactionMode set to Classes:
...
are not the same as the mode set to Addin-Manager.

I tried it out with a completely new project, as I suspected something going wrong with the build process.

    [Transaction(TransactionMode.Manual)]
    public class SomeCommand : IExternalCommand
    {
        public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
        {

            Result result = Result.Succeeded;
            return result;
        }
    }

Fascinating enough, I was able to load the same DLL it into AddinManager in Revit 25.

When I used a 2014 RevitAPI import by mistake and used TransactionMode.Automatic it worked,

Maybe anyone else had that problem and has a solution for me that doesn't involve restarting things? :)
