Copilot cli fails to start without any output when there's a login issue

[PabloZaiden]

Describe the bug

From time to time, copilot fails to start, doesn't print anything in the terminal and just exits with a non-zero exit code.

By trial and error, I've found out that re-running copilot login and going through the auth process again, let me start copilot again without issues.

Affected version

GitHub Copilot CLI 1.0.10-0.

Steps to reproduce the behavior

1. Run copilot
2. Sometimes, copilot terminates immediately and goes back to the shell

Expected behavior

Copilot starts without issues

Additional context

• macOS, latest update.

[Gumbraise]

Same here.
Do you think you jave the same issue as #2225 ?

[PabloZaiden]

Probably. However, I don't have any proxy en vvars

This should be resolved as of v1.0.15. The auth startup path now catches transient errors during token validation and surfaces them instead of exiting silently. Upgrading from v1.0.10 should address the intermittent silent failures you described. If you're still seeing this on a current version, please feel free to reopen.
