RPi 3B+ WiFi drop when second SSID is enabled

I'm using RasberryPi 3B+ with OpenWrt 22.03.5 r20134-5f15225c1e (last version) and have this issue: when I add the second SSID all WIFI stops to work.
I have worked many hours to try to solve but without any result...

I don't know if this is normal but I see 5Gb interface only:

Has anyone solved?

You won't be able to solve the problem because the wifi chipset on the Pi devices do not support running multiple SSIDs on a single radio (and they only have a single radio onboard).

Unless you are using this as a travel router, you should consider a proper AP (or all-in-one wifi router to use as a dumb AP) because the general performance (aside from the issue at hand) is very poor from these wifi chipsets due to multiple factors (low end 1x1 radio systems, small PCB mounted antennas, etc.).
