2 years ago your OpenOCDPath is incomplete...pointing to a directory rather than an executable
"cortex-debug.openocdPath": "/usr/local/bin",Which resulted in this a bad launch
Launching gdb-server: /usr/local/bin -c "gdb_port 50000" -c "tcl_port 50001" -c "telnet_port 50002" -s ~/pico/openocd/tcl -f /home/myself/.vscode/extensions/marus25.cortex-debug-1.4.4/support/openocd-helpers.tcl -f interface/picoprobe.cfg -f target/rp2040.cfgChange it to
"cortex-debug.openocdPath": "/usr/local/bin/openocd",
