    We are attempting to upgrade to Unity 2019 from 2018.3.11, and when we attempt to make standalone (Windows so far) builds, we get the error:
    Copying assembly from 'Temp/Unity.Timeline.dll' to 'Library/ScriptAssemblies/Unity.Timeline.dll' failed

    Sometimes it is a different dll. It seems to randomly succeed on maybe 1/20 attempts. Another engineer has tried to fix this, and he can see the "missing" file in the Temp folder, and then it gets deleted before the error is generated.

    There is a thread with this error in the 2019.1 beta forum, but I'm getting this on 2019.1.0f2.

    Once again I have discovered that the quickest way to solve your own problem is to ask for help. :)
    Noticed this in the editor log:
    [ScriptCompilation] Recompiling all scripts because: Recompiling all scripts before player build because Auto Refresh is disabled.


    Sure enough, turning Auto Refresh back on (which is HORRIBLE from a workflow point of view by the way), fixes the issue. It appears there is a race condition with the script compilation and the player build.
