Unity Issue with Asset Pack

Question

I am fairly new to Unity and when I import this asset pack, my project gains 600+ compile errors with most of them looking something like this:

Library\PackageCache\[email protected]\Runtime\Utilities\Playables\VisualEffectActivation\VisualEffectActivationClip.cs(4,19): error CS0234: The type or namespace name 'Timeline' does not exist in the namespace 'UnityEngine' (are you missing an assembly reference?)

These are the other two errors that are a bit different than the others:

Script updater for Library\Bee\artifacts\1900b0aE.dag\Unity.ShaderGraph.Editor.dll failed to produce updates.txt file

Script updater for Library\Bee\artifacts\1900b0aE.dag\Unity.PackageManagerUI.Editor.dll failed to produce updates.txt file

I have been looking for the fix, but I didn’t find anything.

I am currently on Unity 2021.1.10f.
I have Visual Studio 2017 installed, but I’m sure if that helps or not.

Thanks in advance!

Did you install the Timeline package with the package manager? — Retired Ninja

Have you tried clearing the Library folder inside of the Unity project folder?

First you should close Unity, and go to the Unity Root Project Folder, find the Library folder and delete it.

Done that, reopen Unity and it should re-import everything and hopefully fix the issue!

It can often solve a lot of import errors :)
