The firmware is able to support the channel chanctx up to 2 interface simultaneously running on the different channels. Another thing to be noted is that before the driver is going sent out the management frames, the driver has to get the privilege from the firmware to occupy the current channel context until the frame handshake is completed and then get the privilege back to the firmware. We temporarily disable the feature with a module parameter mt7921_disable_cnm for a while until we can ensure the patchset doesn't cause any regression.
