PPPoE Problem in VLAN facing in Router OS 6.42.7

Dear Team,

We observed one issue in latest version(6.42.7 Current).
PPPoE Users are not connecting on VLAN. When we changed same connection to ethernet it’s working fine.
In logs we are getting connection is active and closing previous connection.

When we downgrade mikrotik os version to 6.29 its working fine.

Please suggest us what we need to change in PPPoE server configuration after upgradation to latest version.

Thanks
