This sounds a lot like a multi-BSS issues that were discovered
recently on AP branch firmware.

See commit:

  ath10k: fix multi BSSID with WPA on FW 10.1

You could try applying the commit and remove the following code from it:

  if (arvif->vdev_type != WMI_VDEV_TYPE_AP)
    return;

The commit was originally only tested against AP interfaces but I was
suspecting the same thing (i.e. corrupted Tx) could be happening on
multi-STA.
