Can not get coverage feedback in V-Shuttle-S

[ZheyuMa]

Environment

1. kernel: 5.10.130
2. OS: Ubuntu 20.04.4
3. gcc version: 9.4.0

Problem

I have built V-Shuttle-S according to the readme and collected the seeds using collect-seed.sh, but I noticed during fuzzing that fuzzer is not collecting coverage feedback, what could be the reason?
Note: I can collect coverage normally when I reproduce V-Shuttle-M.

Could you give me some hints?

No, not yet. I'm waiting for the author's response.
