What's Wrong?

I'm running claude inside a bwrap sandbox.
Versions up to 2.1.119 works fine, but 2.1.120 fails to resume previous session when started with -r flag after choosing the session.
Without -r it starts and /resume inside Claude works.

What Should Happen?

Claude should resume previous session when started with -r flag.
