Without seeing a backtrace it is difficult to tell.

Another issue could be that you use things depending on the ring crate
whose assembly isn't compatible with the new x-only protection on modern
amd64 machines.

If so, you will need to

# pkg_add rust-ring

and replace lines like this

ring = "^0.16"

with something like this in Cargo.toml:

[dependencies.ring]
version = "^0.16"
path = "/usr/local/share/ring-0.16.20"
