I’m afraid to say this is not entirely true.
My problem was that I had AirPods pros that were set to connect to two different devices, my iPhone, and the Mac.
They were set to automatically reconnect to the Mac and as a result if they are on they ping-pong between the two.
For some reason when the Mac connects to them, it loses focus so this is a Bluetooth potential issue as well.
Turning off the automatic reconnection, fix my problem directly while I was testing.
Yes indeed, there seems to be multiple issues causing the same symptom. My post was trying to emphasise that there are other causes for the same symptom as well as Bluetooth.
I have now confirmed for sure that it was Logitech G-Hub causing loss of focus on my own Mac Mini desktop, simply by stopping G-Hub. I'm no longer seeing the issue after waking up the computer after it has been in sleep mode. (which is when the issue had been kicking in for me)
The thing that Logitech G-Hub has in common with other software is that it runs a background service that monitors mouse and keyboard input. That seems to have started malfunctioning after Tahoe was patched.
Regarding Bluetooth, I found that Bose multi-path Bluetooth simply doesn't work with Apple devices anyway, even before Tahoe. When I have my headphones paired with both my iPhone and Mac Mini the audio tends to break down into unintelligible noise, and can only be fixed by fully reconnecting. Used to happen with my old Intel Mac Mini and still happens with the M4 model. So I've stopped usign multi-path and only pair with one device at a time.
