Using the debugger as well-known for years ;-)

Actual behaviour

I am having a small issue with the latest version (2020.5.86398 (8 June 2020)) of the Python extension debbugging ROS node. I have deinstalled ROS, VSCode and Python2.7 in generall. After few moments I have figurered out, once I downgrade to the Python extension (2020.5.1 (19 May 2020)) it works fine.
.

Every time I start the debugger running my code it crashes resp. it stops as shown in the figure. A workaround for me is, to install the previous version and disable auotmatic updates...

Steps to reproduce:

• Install ROS Meldodic Desktop Full
• Run roscore
• Run a simple ROS Node ROS Node with the debugger

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

This is most likely microsoft/debugpy#281

If so, try unchecking "User-Unhandled Exceptions" in the Breakpoints pane.
