    Ahh so this is the package and bug that caused me the pain of 16 hours of retrying editor installations. I'm sure everyone else dealing with this is assuming the packages should work if 3D URP works without issues. There's no way to know till you get here.

    Because of this bug if you want to setup your project with 2D you have to delete/reset all 2D packages and install everything manually AFTER installing DOTS packages first. On top of that you have to avoid this specific 2D animation package when reinstalling everything so you cant grab it all from 2D features package.

    From the looks of it you only need com.unity.2d.common as it also will grab sprites and that's really all you need besides the URP package.

    Unity should really consider acknowledging this bug exists in the 1.0 prerelease docs. That's only fair to users and testers who might happen to use 2D and incidentally waste tons of time not knowing about this. Please give this feedback some consideration and thanks for your time and hard work.

    Also experiencing this issue.
    Probably they're focusing on the 3D DOTS compatibility because this is where you can have the biggest performance increases. I would like to experiment with DOTS in 2D and see if it can make code in general easier.
