Error while starting zigbee-herdsman

[tepid smelt]

Got this error-message out of the blue:

If I start "terminal" in Home-Assistant and run following:

/bin/bash
ls -als /dev/ <tab><tab>

I don't see any "serial-device" directory at all below /dev

Any Idea why this happend out of the blue. Since some days ago, anything work like a charm

What installation method and hardware do you use?

[tepid smelt]

I have HA installed on a raspberry pi, with an Zigbi-usb-stick (Slaesh CC2652RB).

This are the part of my zigbee2mqtt/configuration.yaml, which work at least (but not anymore):

devices:
  - devices.yaml
groups:
  - groups.yaml
homeassistant:
  enabled: true
mqtt:
  base_topic: zigbee2mqtt
  server: mqtt://1.2.3.4:1883
  user: <user>
  password: <myPasswd>
serial:
  port: >-
    /dev/serial/by-id/usb-Silicon_Labs_slae.sh_cc2652rb_stick_-_slaesh_s_iot_stuff_00_12_4B_00_23_93_35_53-if00-port0
  adapter: zstack
  disable_led: false

I wonder why all the Block-Device entries in HA are gone.
I remember that I have adjusted them a week ago, and there /dev/serial/by-id/ still exists... now its gone.
