Bug#1032995: spyder: Spyder on startup says there is a missing dependency (pylsp_black) but it is correctly installed

Oh, this is so bizarre!  Let's try a sledge-hammer approach....

Assuming that you have the strace package installed, could you try
this and send the resulting log file (/tmp/spyder-trace.txt.gz); you
will need to wait at least until the warning message about pylsp_black
appears:

strace -f -o /tmp/spyder-trace.txt -s 256 -e openat,read spyder

gzip /tmp/spyder-trace.txt

Hopefully this will give a clue to where this strange behaviour is
coming from!

(BTW, this log file will include the first 256 characters of any files
you open, so I recommend you do this with a clean spyder profile.)

Best wishes,
