I've hit this problem on 13.1-RELEASE arm64.
Comment 2 Mateusz Piotrowski freebsd_committer freebsd_triage 2023-02-13 10:54:49 UTC 
One of the reasons for the pid provider being unavailable is that the AArch64 fasttrap code is not implemented. See sys/cddl/contrib/opensolaris/uts/aarch64/dtrace/fasttrap_isa.c.
