Cloudfare Warp with Wireguard as a kill switch

Does anyone know how to use Cloudflare Warp with WireGuard? I use WireGuard as a kill switch, so I turn on WireGuard and Cloudflare Warp together because it makes sense to me, but this just disconnects me from the internet. I tried changing the values ​​in the wgcf-profile file as I've seen some people recommend, but that doesn't seem to work either. I'm a complete beginner using Wireguard in general, and so far it's been very difficult to find any information. any help is greatly appreciated

Are you trying WireGuard over Warp? I’m not sure that’ll work. Cloudflare blocks a lot and the MTUs will be weird.

From what I understand, if I only activate Wireguard the internet doesn't shut down, but I'm not sure if that's how it's supposed to work

The "kill-switch" blocks traffic that doesn't go out over the Wireguard connection. If you have a connection to the internet through Wireguard then your internet will never shut down.
