What causes a message indicating that the terminal cannot join the network after WiFi broadcast?

The wifi broadcast is normal, but the terminal cannot join the network when it accesses the network

Right SSID? Right password (assuming PSK authentication)? Right certificate (assuming cert-based authentication)? Compatible frequency? Compatible encryption?

Open WiFi, unencrypted. but a message indicating that the terminal cannot join the network is displayed when the terminal is connected

No available addresses in the DHCP pool? No DHCP server configured? DHCP server crashed?

At first I also suspected a dhcp problem, but I have two wifi modules here, the same hostapd.conf configuration, the other one is fine. So I suspect that it is the problem of this wifi driver, but I have not located the problem of the driver. Now I am ready to use the wifi packet capture tool to look at the negotiation process of the device connection

Please run the following commands (copy-paste the whole block) and paste the output here, using the "Preformatted text </> " button:
Remember to redact passwords, MAC addresses and any public IP addresses you may have

ubus call system board; \
uci export network; uci export wireless; \
uci export dhcp; uci export firewall

The platform is not a generic platform supported by openwrt, we are porting openwrt's network and wifi framework.
The network configuration should be fine, I've verified it here with other wifi modules

If you don't provide much information, there is only guesswork we can do here.
