I have a LINKSYS EA7500-V1:
when the router is running 23.05.5 , wan port is working the router get a IP and everything is working .
when the router is running SNAPHOT , wan port does not work , he can send packets , but does not process received packets.
the router can not process DHCP reply .
This is happening without any changes in the configuration .
i created this issue : https://github.com/openwrt/openwrt/issues/16604

Nothing looks out of place here... but a few thoughts:
Do you have another router that you can try upstream of this EA7500? Specifically, if you connect the wan of this device to an upstream LAN where there is a DHCP server, does it obtain an IP address?
What type of physical internet service do you have? (Cable/DSL/Cellular/Fiber/etc.). If the MAC address of the EA7500's wan port has changed due to the upgrade (there are a number of reasons that this could happen), it may not get an IP from the upstream service until the previously "learned" MAC address is cleared. Have you tried doing that?
I can see the dchp uplink reply .
The EA7500-v1 is running in a lab context .
This is a network diagram
EA7500-V2 is working and can get a DHCP address
EA7500-V1 is not working and can not get a DHCP address

Is the Mini PC running a DHCP server? Or is that upstream on port 1 of the switch?
What do you see in the v1:
logread -e udhcpc
I did notice the mac addresses for LAN and WAN
are the same witch flags a problem to me
ea7500 and ea8500 but this was v23
The same MAC on the wan and lan actually doesn't cause a problem. That's because the only critical rule for MAC addresses is that each device has a unique MAC on their respective networks.
dhcp server is outside of the diagram feeding via port lan1

And if i set a static IP , that does not work too .
i did a test , and change the mac address for WAN , from 1X:XX:XX:XX:XX:Xc to 1X:XX:XX:XX:XX:Xd .
That's work , so this is a work around .
I tried 23.05.5 , 23.05.2 this is working without changing the mac address .
@Lucky1 do you remember in which version you had / see the problem ?
@Ansuel may be you are interessed by my problem !
I need to manually to change the mac address .
@bdleonard , just saw your post Linksys EA8500 issues on recent snapshots
I went from V19 to V23 so an early v23 .0 or .1
I think it was firewall related but can't remember
just know from then on I just make sure all the MAC addresses are different
and the problems go away so always had it changed since
