Debugger starts only once on Windows

[Slion]

Pico W + Debug Probe + Windows 11 + Pico Visual Studio from Pico Setup The probe is updated to the latest firmware. Looks like that issue is specific to tinyusb_dev_hid_composite example. The Pico W blink example works just fine.

I can start the debugger once and it seems to work fine. Then when I stop it the probe's yellow LED stays on. Trying to restart it gives me OpenOCD timeout:

The only way to get it to work again is to reboot both Pico W and Probe.

pinging @ndabas in case he has any suggestions

I'll have to try this out and see if I can replicate it. From the looks of it, it doesn't seem to be a Windows-specific issue ("probe's yellow LED stays on" and "Error: unable to find a matching CMSIS-DAP device".)

It's possible that something we're doing on Windows isn't closing the debugger connection cleanly though, so I'll take a look.
