Error Wifi EA7500v2

I am using the 5GHZ network and (OpenWrt 21.02-SNAPSHOT r16235-8921e36ed8 / LuCI openwrt-21.02 branch git-21.191.52202-07063ae)
I need a client mode and an AP mode but it does not allow the creation of both, it generates disconnection every 10 seconds, it allows creating two or more in AP mode or two or more in client mode but not invited.

Does anyone know why this error happens?
It has a solution?
