Start by reading route/dns.go:91, where the nil receiver appears in the panic, then trace the UDP path through sing-tun's stack_gvisor_udp.go:52. The report says the failure cannot be reproduced, so first determine the conditions that leave dnsHijacker nil using the supplied DNS, fake-IP, and TUN configuration. Done means the cause is identified and the same path no longer crashes, with regression coverage if reproducible.
