When trying to run fwupdmgr, it hangs. journalctl: Nov 12 12:07:55 lap dbus-daemon[433]: [system] Activating via systemd: service name='org.freedesktop.fwupd' unit='fwupd.service' requested by ':1.104' (uid=0 pid=38477 comm="fwupdmgr refresh> Nov 12 12:07:55 lap systemd[1]: Starting Firmware update daemon...

Downgraded to 1.9.24, this one works fine.
