ASUSWRT device tracking is not working when restart HA

Today, I just upgraded HA version to HA2021.1.0. When I first restarted HA, asuswrt was running normally. Then I updated the built-in integration configuration of BMW. After restarting again, the asuswrt was invalid & appeared the error message above

The Problem:

There is an issue with ASUSWRT integration.
Every time after HA is updated, ASUSWRT can work normally when it is restarted for the first time. However, if HA is restarted artificially after that, ASUSWRT will fail to work normally due to errors

Is there a problem with the version of aioasuswrt again?
