"default traffic shaping rules" delay video conferencing?

[Snika]

"Default Traffic shaping rules" is enabled in MR.

There is no problem in daily life, but there is a severe delay when video conferencing with Google Teams.

Are video conferencing delays related to the "default traffic shaping rules"?

Note that QoS settings do nothing unless there is congestion.  Once congestion has occurred and there is a queue of packets then QoS can re-order those packets.  If there is no queue of packets waiting to be sent there is nothing to act on.

Is your Internet circuit being maxed out at any point in time?

How to check packet queue and congestion?

Have a look at your uplink graph and see if the circuit is maxing out.
