No internet after upgrading to pfsense 23.01 plus

hello
my setup
bare metal system for pfsense

tried a fresh upgrade…removed old boot env of 23.01, removed ntop package.
upgrade went fine.
but again got the same issue…
-there is net connectivity for 1-2 min after boot and then it goes down.
-CPU speed is throttled

Have wireguard and tailscale installed
no HAproxy/openVPN/pfblocker installed

when i switch back to 22.05 using boot env with same config everything works.

got some logs
