Debugger VERY sensitive to shutting down??

I am using an STLINK-V3SET programmer / debugger. I connect to my target (STM32WB55) on a Midatronics Sharky Mkr board. I find that if I 'blink' or move funny the debugger after connecting shuts down and displays the following under the console window:

Target is not responding, retrying...

Target is not responding, retrying...

Target is not responding, retrying...

Target is not responding, retrying...

Target is not responding, retrying...

Target is not responding, retrying...

Target is not responding, retrying...

Target is not responding, retrying...

Target is not responding, retrying...

Target is not responding, retrying...

Shutting down...

Exit.

Can someone help me out here as to what to do?
