upgrade to 24.1 -> default route broken

[bazbaz]

I've just updated from the last 23.7 to 24.1. After the upgrade, I was able to access the firewall from Internet, but the firewall itself was not able to send packet to any host. The default route was not loaded in routing table, or better it was loaded but assigned to a wrong interface (an ipsec).
The upstream gateway setting was preserved in WAN interface.

I manually added a static route 0.0.0.0/0 to the default upstream gateway and this solved: the right default route is loaded, and the wrong is not reported.

I upgraded many firewalls to 24.1 without this problem, but I'm worried because this is the most important. Is this a known issue? Is this something I can check?

wan is an IPv4 only interface with static public IP. OpnSense runs on a VM

thanks
