SLAVE replication breaks with mariadb master running on version 10.6.5

We recently updated our mariadb master from 10.5.10 to 10.6.5 and since then started experiencing some random replication failure on our slave nodes.

However Slave nodes running version 10.6.5 but replicating to older 10.5.10 mariadb master works just fine.

Replication breaks around 4 times now (exactly at a binlog offset position 4) since the last 5 days after upgrading master to version 10.6.5.
In case it helps: We have multiple clients connecting to the master node and experiencing similar problem.

Logs during two such incidents as below:
