Weird.
After - though not expecting anything to change - trying your suggestion a second time:

This time the following popped up, not in the minibuffer, but in the same buffer "scratch", just after the last ")" in your command:
"\\wsl$\Debian\home\citizen13"
CMD.EXE wurde mit dem oben angegebenen Pfad als aktuellem Verzeichnis gestartet.
UNC-Pfade werden nicht unterstützt.
Stattdessen wird das Windows-Verzeichnis als aktuelles Verzeichnis gesetzt.
Microsoft Windows [Version 10.0.19044.1889]
(c) Microsoft Corporation. Alle Rechte vorbehalten.
C:\Windows>
Quick & dirty translation:
CMD.EXE was started with the above stated path as present directory.
UNC-paths are not supported.
Instead the windows-directory is being set as present directory.
Microsoft [...] etc.
(c) [...] All rights reserved.
C:\Windows
Makes a non-technical person wonder: May this be considered a success or the contrary?
