Some of your settings even before you get to AiMesh issues don't make much sense to me. You have WPA2/3 transitional, WPA3 requires PMF, Wi-Fi 6 is enabled on 2.4GHz band most likely in B/G/N/AX Auto, IGMP snooping is enabled, TX bursting is disabled... and you have a bunch of IoT devices which support none of the above and such settings can only make it worse. On 5GHz you push 160MHz wide Auto channel for unknown to me reason, it may only generate higher speed test numbers in expense of lower reliability and range.
