{"body":"### What happened?\n\nRunning `pi --resume` and pressing <kbd>Escape</kbd> leaves the app in an unusable state.\n\n### Steps to reproduce\n\n1. Run `pi --resume`\n2. Press <kbd>Escape</kbd>\n\n\n### Expected behavior\n\nThe app exits or a new session is started. Instead, \"No session selected\" is printed and the app stops responding to keys. The only way out is to SIGINT <kbd>Ctrl+C</kbd> and restart the app.\n\n### Version\n\n0.49.1","comments":[],"labels":[{"id":"LA_kwDOPbFNk88AAAACHWTBxw","name":"bug","description":"Something isn't working","color":"d73a4a"}],"state":"OPEN","title":"Soft lock in \"pi --resume\""}

This is a bug report about pi --resume soft-locking when pressing Escape. Let me read the relevant code files to trace the issue.
