With the release of Zibee2MQTT 2.0.0 anyone using a CC2652P2 or P7 based adapter will need to adjust their Zigbee2MQTT configuration.yaml or Add-On Settings. Without this update Zigbee2MQTT will fail to start.
You simply need to add one line under your serial port configuration.
serial:
port: tcp://IP_ADDRESS:6638
adapter: zstack # <-- Add this line
If using the Zigbee2mqtt add-on, you should edit the Serial settings section and add the adapter line:
