I am trying to debug some code on a Raspberry Pi Pico W. I'm using PlatformIO. After some Issues with the OpenOCD version shipped with PlatformIO (Access Violations), which I fixed by replacing the OpenOCD with the version shipped with the Pico SDK I'm now facing the Issue that I'm here to ask about.
For some reason I get a error about two or more SWD non multidrop DAPs being not supported. I'm unable to find anything usable about this error online.
Here is the exact error message:
Error: Two or more SWD non multidrop DAPs are not supported
and here the wholeoutput:

What I've already tried:
- reflash Pico probe
- update PlatformIO (already newest version)
- check all connections for contact
- check power delivery to the debug target
- check that the correct pins are connected

PS: I'm new to microcontroller development so I'm sorry if I made some dumb mistake.
