Since I am not totally sure about the useful information, let me show you
the kernel logs:
$ dmesg | grep ath11k

If I try to setup 2 APs with your interface combination I get this:
# iw list | grep -A6 "valid interface combinations:"
	valid interface combinations:
		 * #{ managed } <= 2, #{ AP, P2P-client, P2P-GO } <= 16, #{ P2P-device } <= 1,
		   total <= 16, #channels <= 1, STA/AP BI must match, radar detect widths: { 20 MHz (no HT), 20 MHz, 40 MHz, 80 MHz, 80+80 MHz, 160 MHz }

		 * #{ managed } <= 2, #{ AP, P2P-client, P2P-GO } <= 16, #{ P2P-device } <= 1,

If I use the parameter to ignore the feature and configure the interface combination as before:
# iw list | grep -A4 "valid interface combinations:"
	valid interface combinations:
		 * #{ managed } <= 1, #{ AP, P2P-client, P2P-GO } <= 16, #{ P2P-device } <= 1,
