14.1. Another bug?

I left DaVinci overnight to do its stabilization thing. When I came back, both video and audio tracks were locked, and there is no way to unlock them. Color grading can still be performed, but no editing and no Fairlight, obviously. Trashing the project and starting all over is certainly an option, but I really do not want to spend another 24 hours stabilizing. What do I do now?

Have checked the Lock icons on the tracks to be sure they somehow weren't toggled on by mistake?

Right... Checked door locks too.

Silly question but I take it this isn't a master timeline?

What happens if you duplicate the timeline and unlock the duplicate?

of course it was the master timeline

Thank you Marc, it did the trick. The copy of the master timeline was successfully unlocked!

The question still stands: what the hell happened?
