My issue is similar I see these errors:

libbpf: Error loading ELF section .BTF: -22. Ignored and continue.
libbpf: failed to create map (name: 'ctrl_map'): Operation not supported
libbpf: failed to load object 'rss_kern.o'

solve the issue by

xdp_flags = XDP_FLAGS_HW_MODE;   =>   xdp_flags = XDP_FLAGS_SKB_MODE;
