I use sudo sh libnyx/libnyx/tesh.sh (https://github.com/nyx-fuzz/libnyx/blob/main/libnyx/test.sh) command to fuzz nyx_tinydtls (obtained from https://github.com/RUB-SysSec/nyx-net/tree/main/targets/packed_targets). But the result nyx_exec (C interface nyx_exec in https://github.com/nyx-fuzz/libnyx/blob/34679b90dcdcc3c9834e4a510e6fc3ebb77b2246/libnyx/src/lib.rs) is always equal to 1. And I use nyx_print_aux_buffer (C interface in https://github.com/nyx-fuzz/libnyx/blob/34679b90dcdcc3c9834e4a510e6fc3ebb77b2246/libnyx/src/lib.rs) to get the result which shows HYPERCALL_KAFL_PANIC_EXTENDED: assert: setup_interpreter src/ld_preload_fuzz.c 325: offsets[0] == 1840245495844197195ULL. Here are the results snapshot. I don't know how to solve this problem. Looking forward your reply. Thank you!

Hello, how do you quickly start using these APIs? I can't understand how to use APIs to create and restore snapshots
