The first command simply tries to reference /b (folder 'b' in the root directory of the OS). It fails because the directory you run kemono-dl from is ALWAYS appended to the front, so /b becomes {current directory}/b instead of root-directory/b.
The second command fails because kemono-dl tries to write debug.log in {current directory}.
Error messages and tracebacks
Off the first command, there are no errors, per se. Files download, but into the wrong directory (into /home/catthou/b/... instead of /b/...)
Off the second command, we crash because we can't write the log file to the root directory:
Traceback (most recent call last):

Additional comments
Dumping a file with a non-descriptive filename (debug.log) in a random directory is bad practice to begin with. At the very least it should try typical log directories (like /var/log or $XDG_CACHE_HOME/kemono-dl) and use a name that indicates who's writing it. $XDG_CACHE_HOME/kemono-dl/debug.log or /var/log/kemono-dl.log would be two practical, expected filenames for logs on linux.

Your Command
Two particular commands fail.
The above command fails to write the file into /b/... and instead writes it into {current directory}/b/...
Next we try to cd into the root directory so {current directory}/b is /b, but this fails for a different reason:
