This continually happens when I'm initially starting my development and mostly for the first time Running the app in Debug mode.
I run it again and the app starts up.

This never used to happen during development testing.

For some reason the app crashes in debug mode, at startup. If the project is not too complex then you can send it to me and I'll check it. I would be happy to solve this issue.

Hi Erel. Notice it's a Connection Reset, referenced a few times.
So what is getting reset and why?

BTW... I'm testing on 2 devices, not all the time, but now and then.
I notice the reset happens after leaving the computer for a few hours then going back it it to continue my work.
I leave the connection between the IDE and the device "on". I'm in the living room and the computer is in the front room - maybe 20-30 away, and I notice my device has lost its connection.
Could this be the reason for the reset?
Also the connection resets sometimes when I switch devices for testing.
I click on the Clean menu option a couple of times and most of the time that takes care of it.

Hard to say.

It might be related to a real network connectivity issue, but it can also happen if something is causing the debugger crash during startup. You can distinguish between the two cases by testing it with a simple project. If it still fails then it is likely to be a network issue or an antivirus that decides to break the network connection.
