Actual Behavior

All tabs are hidden and cannot be selected.

Screenshots

Browser Version

Operating System

Windows 11 25H2

Additional Context

I cannot reproduce it on a fresh profile, even when trying to match settings/hub.
Have also tried to match the number of tabs in my workspaces (have 2x), but not the URL:s of the tabs.
The issue persists in Troubleshoot Mode.
