Assembly has reference to non-existent assembly 'Unity.ugui' (Packages/com.unity.textmeshpro/Tests/Editor/Unity.TextMeshPro.Editor.Tests.asmdef) This is the error i had when i import a package to an empty unity project. Unity version was 2018.3.0.f2. Solution is simple i think. Goto: Help -> Reset packages to default. Click yes It resolved my issue. Please write in comment if you solved it with other solution, others can get help :) also subscribe my blog
