The target scripts rp2350*.cfg files in %LOCALAPPDATA%\VisualDGB\EmbeddedDebugPackages\com.sysprogs.arm.openocdcom.sysprogs.arm.openocd\share\openocd\scripts\target are missing in the above version of OpenOCD. Copying them from the previous version to the target directory resulted in everything working normally as far as I can tell.
