Netgear D7800: missing directory

Trying to compile openwrt 23.05 for Netgear D7800, I'm getting
openwrt/staging_dir/target-arm_cortex-a15+neon-vfpv4_musl_eabi/usr/include: No such file or directory [-Werror=missing-include-dirs]

Indeed there is no such folder.

.config file:

https://pastebin.com/MpsuWiUa

Any idea why?

Ok, never mind that.
Since I already succesfully compiled 22.03.4 and still have all the relative files maybe I could use the old .config file some way but I'm not familiar with this, how should I proceed please?
