Hey, this is a known bug in 2.6.20 and it’s already being tracked here: Run and Debug controls missing from Run and Debug panel in 2.6.20
It happens when the activity bar is in vertical mode. Two workarounds until the fix is out:
- Settings > search for “activityBar orientation” > switch it to
horizontaland the run/debug buttons should come back. - Or use
Cmd+Shift+P> “Debug: Select and Start Debugging” to start configs from there.
Let me know if the workaround doesn’t help.
