Synology Update to DSM 7. Zigbee2mqtt does not start anymore

[Hohenbostler]

Hello I kind of need urgent help.
I have been running Zigbee2Mqtt for a good 2 months. It is the following LAN Stick: Zigbee LAN/USB/WLAN Gateway CC2652P
The reason why I chose this is that I have iobroker running on a Syno 218+ and because of the USB problem and DSM 7 I can't use a USB stick anymore.
The system ran largely without problems. Until today. Today I did an update to DSM 7 and now nothing works anymore the Zigbee2MQTT container just won't start.
As an error I get the following:
Using '/app/data' as data directoryZigbee2MQTT:error 2023-05-22 15:39:55: Not connected to MQTT server!Zigbee2MQTT:error 2023-05-22 15:39:55: Cannot send message: topic: 'zigbee2mqtt/bridge/state', payload: '{"state":"offline"}TypeError: Cannot read properties of undefined (reading 'end')at MQTT.disconnect (/app/lib/mqtt.ts:129:21)at Controller.stop (/app/lib/controller.ts:198:9)at stop (/app/index.js:111:5)at process.handleQuit (/app/index.js:117:9)

The container goes off again immediately. I have not changed anything in the configuration.yaml and the web interface of ZIgbeestick itself is also accessible via the IP by default and the settings are untouched.
Does anyone have an idea how I can solve the problem ?
