    Hello,
    I've seen the other Threads of : "An item with the same key has already been added"
    But my Problem occured while working on Timelines.
    I made Emty Objects and attached playable Assets to them. When I finished making timelines, I tried to share them with my teammate via Collab. Then Collab would stay blank without any buttons. After I restarted it, it would open, but I can't publish anything, it won't even let me write a summery. But History still showes up.

    ArgumentException: An item with the same key has already been added. Key: Assets/Art/Charakters/szene1 part1/TimelineZusammenfügenalerAnimationenTeil2_ANI_v001.playable

    This Error popped up, and when I remove a Timeline the error starts reffering to another timeline. I think it's something about all timelines in general.
    I'm new to unity and it seems like I can't find a fix.
