diag/setLogger has confusing warning which seems like an Error when logger gets overwritten.

Log sample:

As you can see in the above log, the first line ends with 'Error' keyword.

I think the below code cause this issue. Stack variable seems to start with Error

        const stack = new Error().stack ?? '<failed to generate stacktrace>';
        oldLogger.warn(`Current logger will be overwritten from ${stack}`);
        newLogger.warn(
          `Current logger will overwrite one already registered from ${stack}`
        );

Hi @altinokdarici - there was an option added a little while ago via #3366 called suppressOverrideMessage to silence this log. Does that work for you?
