Long (45-60 second) delay after hitting "Play" in Unity Editor if VisualStudio debugger is running

This just started happening within the past week or so. Just a guess, but possibly related to upgrading my version of VisualStudio (MacOS) to 8.3.8 (build 10). Unity version is 2019.2.6f1 Personal.

Within the Unity Editor, if I hit the “Play” button, my app begins executing almost immediately (perhaps a delay of 3 or 4 seconds). However, if I first hit “Run” within VS with the “attach to Unity” option (in order to debug) and then switch to Unity and hit “Play”, there is a long delay of between 45-60 seconds before the app begins to run. As I said, this is something new. A week or two ago there was hardly any delay.

Any ideas on what might be causing this delay or how to isolate the problem?

This is a major speedbump anytime I need to debug. Is this something that should be submitted as a bug report? Again, prior to a couple of weeks ago, this long delay wasn’t present.
