Could not find kallsyms_names for Ubuntu Kernel

I receive the following error when trying to use the project on Linux v6.5.0, which is Ubuntu's kernel.

Yo @Kyle-Kyle,

I ran into the same issue for a 4.4.23 kernel extracted from an Android phone. Did you manage to work around this?

@0ddc0de yoyo! Unfortunately, I don't remember what happened afterwards. My guess is that I didn't solve the issue..
