    Hey there, exactly the same happens for me. When I try to make a Dolly Camera with Track, I can't seem to record.

    With which Unity version? Also, what is the Timeline package version (you can get that information in the Package Manager window).

    Any more info on this? I got this on 2019.2.18f1 today with Timeline 1.1.0. First time trying out timeline so a little at a loss at where to go from here.

    A simple restart of Unity seemed to fix it for now for me.

    The error seems to be related to your current layout. As a workaround, if it happens again, try reverting your current layout.

    Resetting the layout works for a while, but the error resumes some arbitrary time later. We cant isolate it to a particular window being open or not.

    This issue still exists in 2019.4.13f1 and Timeline package v1.2.17. I was able to resolve by resetting the editor layout.

    This is a known issue - as of right now, the issue is currently marked as won't fix. Resetting the layout is the recommend workaround - we have had a difficult time getting a consistent repro project.

    If resetting the layout does not fix the issue, please submit a repro project so we can reopen the issue and deliver a fix.

    As stated above, we have not been able to reproduce the issue. If you have a repro case, (including layout files) please submit them.

    Small update on this. Literally - a couple hours after posting 2 separate people at Unity starting experiencing this. So, we have a valid repro case and have reopened the bug.

    With luck we will have a fix soon.

    Can confirm setting your layout to default fixes the problem

    A new Installation of the current Unity version you are using will also fix the problem.

    Helped me a few weeks ago.

    So, if I am still having this in unity 2019.4.2 (LTS) and reverting the layout to factory doesn't help, that's bad news, right?

    Oh, and when I open the timeline tab after having reverted, I get this error immediatly:

    ArgumentException: Getting control 2's position in a group with only 2 controls when doing repaint
    Aborting

    Same here, this happens to me in Unity 2020.3.0f1, resetting the layout doesn't help.
