Hey, thanks for the report. This is a known bug with /btw, and it’s fixed in CLI builds from July 17 or newer.
Looks like the session that crashed was still running on an older binary the July early build, even though cursor-agent --version already shows 2026.07.23-e383d2b with the fix. This can happen if the CLI updated, but the running process or session stayed on the old version.
What to do:
Fully quit cursor-agent close all running sessions.
Check the version: cursor-agent --version it should be 2026.07.17 or newer.
Start it again, then run /resume and /btw.
After restarting with the latest binary, /btw should work. If it still happens on 2026.07.23-e383d2b, send a fresh Request ID from that session and we’ll dig deeper.
