this is interesting ... this means EHT MCS verification in ieee80211_verify_sta_eht_mcs_support() fails.

if AP IEs contain EHT operation (I guess so) then this means AP requires NSS larger than 2 in its 'Basic EHT-MCS And NSS Set' field, because WCN7850 supports 2 RX/TX streams for all MCSes (0-7, 8-9, 10-11 and 12-13). so can you check/confirm this? you may add some logs in that function or just check air sniffer if possible.
