Yes, it appears the issue is resolved for me now as well, also without changing anything.

I'm encountering the exact same issue since yesterday afternoon using 1Password with a 1Password Service Account.

We were also using an older version (v2025.2.29.0) when the issue started and upgrading v2026.1.14.0 did not resolve the issue.
