What stands out is: seccomp prevented call to disallowed arm64 system call 434
This is a Samsung Note 9 with Enforcing

[Asutorufa]

I have no idea about this error, I have Samsung tab s9 with oneui 6.1, it's no problem for me.

[gbraad]

On my Tab S6 it starts. The Note 9 is still on Android 10. I might spend some time to get more information and/or solution.

[Asutorufa]

It seems seccomp not allowed syscall pidfd_open.

https://www.chromium.org/chromium-os/developer-library/reference/linux-constants/syscalls/#aarch64_434

which is issue of golang, it already fixed at golang/go@a3a05ed, we should build it with latest golang.

[Asutorufa]

The fixd maybe released with next go version(1.23.3), currect can try build with go dev branch.

https://github.com/golang/go/commits/release-branch.go1.23/

The issue introduced at golang/go@750738b. Older go version(before go 1.23.0) seems no problem.
