ls: cannot access '/keybase': Transport endpoint is not connected

Describe the bug

I cannot access files from CLI at /keybase, however it seems /run/user/<user>/keybase/kbfs shows the files - Debian unstable 6.4.0-20240821175720.3212f60cc5 (I tried also nightly, the same); however, during the installation there was some warnings:

Warning: program compiled against libxml 212 using older 209

jiri@t14s:~$ findmnt | grep keybase

To Reproduce
Steps to reproduce the behavior:

1. Debian Unstable

3. run_keybase
4. ls /keybase/private/<user>

Expected behavior

Files should be visible.

Additional numbers

Start with the run_keybase entry point and compare the findmnt, /run/user/1000/keybase/kbfs, and /keybase outputs shown in the report. Investigate the Debian package setup and the reported libxml warning. Done means files are accessible through /keybase after running run_keybase on Debian unstable.
