python debug "timed out waiting for launcher to connect" #98757
Description
Issue Type: Performance Issue
Any time running with a moderately loaded set of applicatations, especially when running virtual meeting sessions (e.g. Teams), it's not possible to run python debug sessions. The session times out waiting for the python process to start up. This occurs consistently, after all extensions have loaded.
The configuration is nothing special -- default launcher.json -- running one python file in the integrated terminal, Python 3.7.3, anaconda install. The process Explorer shows moderate loads - memory and cpu are around 60 %.
Running MSFT enterprise current Windows 10 on a 16G Dell laptop.
