OpenWrt 22.03.0-rc4 fourth release candidate

Have some strange issue with NAT on the TOTOLINK X5000R
I have two different subnets on the router.
The one is just br-lan with static IP and gateway, it's linked with some wireless networks, there is no DHCP and no NAT.
The second network is connected to WAN and the WLAN NETWORK, WLAN is using "unspecified device" network for NAT, there are static IP on this network and DHCP enabled. This configuration works on the 21 versions and not working on the 22.x.
The problem is that in second subnet, clients are successfully connected to wireless network, getting IP, but can not connect to WAN, no internet, NAT is broken. I have tried clean install, tried all options, no luck. Any thoughts?
