bwrap namespace error when using apply_patch

What version of the Codex App are you using (From “About Codex” dialog)?

0.116.0

What subscription do you have?

plus

What platform is your computer?

linux

What issue are you seeing?

Since my last update of codex I get the error:
bwrap: No permissions to creating new namespace, likely because the kernel does not allow non-privileged user namespaces. On e.g. debian this can be enabled with 'sysctl kernel.unprivileged_userns_clone=1'.
making apply_patch non-working. codex therefore falls back to using perl for file edits.
apply_patch was working fine before the update though, so I think this is a codex bug.

What steps can reproduce the bug?

Trigger a workflow with apply_patch.
