Edgerouter-X no network after including several packages in build

Hi,

I build an image for my edgerouter-x with no additional packages whatsoever and after flashing the device works just like it's supposed to. Reachable via 192.168.1.1.

When I build with some additional packages and flash it to the device the router isn't reachable.
I'm on commit ba3d1407c065bed7df6857054ff4a9aae045387c and this is the diffconfig.

CONFIG_PACKAGE_luci-lib-nixio=y
CONFIG_PACKAGE_luci-mod-admin-full=y
CONFIG_PACKAGE_luci-mod-network=y
CONFIG_PACKAGE_luci-mod-status=y
CONFIG_PACKAGE_luci-mod-system=y
CONFIG_PACKAGE_luci-proto-ipv6=y
CONFIG_PACKAGE_luci-proto-ppp=y
CONFIG_PACKAGE_luci-proto-wireguard=y
CONFIG_PACKAGE_luci-ssl=y
CONFIG_PACKAGE_luci-theme-bootstrap=y
CONFIG_PACKAGE_mkf2fs=y
CONFIG_PACKAGE_mtr=y
CONFIG_PACKAGE_nmap=y
CONFIG_PACKAGE_openssl-util=y
CONFIG_PACKAGE_openvpn-openssl=y
CONFIG_PACKAGE_px5g-mbedtls=y
CONFIG_PACKAGE_rpcd=y
CONFIG_PACKAGE_rpcd-mod-rpcsys=y
CONFIG_PACKAGE_rpcd-mod-rrdns=y
CONFIG_PACKAGE_screen=y
CONFIG_PACKAGE_socat=y
# CONFIG_PACKAGE_swconfig is not set
CONFIG_PACKAGE_terminfo=y
CONFIG_PACKAGE_tinc=y
CONFIG_PACKAGE_uboot-envtools=y
CONFIG_PACKAGE_uhttpd=y
CONFIG_PACKAGE_unbound=y
CONFIG_PACKAGE_vim=y
CONFIG_PACKAGE_vnstat=y
CONFIG_PACKAGE_vnstati=y
CONFIG_PACKAGE_wireguard=y
CONFIG_PACKAGE_wireguard-tools=y
CONFIG_PACKAGE_zlib=y

The image growth from ~ 3,5 MB to about 9,5 MB with those packages included.
Is it because CONFIG_PACKAGE_swconfig is not set? If so, how come it's deactivated? I did not deactivate it manually though.
