In my project, the package manager window is black. I don’t remember when it started.
Also, the following error is displayed:
Cannot perform upm operation: Cannot
read property ‘map’ of undefined
[NotFound]
UnityEditor.EditorApplication:Internal_CallUpdateFunctions()Error searching for packages.
UnityEditor.EditorApplication:Internal_CallUpdateFunctions()
It will be displayed correctly in new projects.
Does anyone know a solution?
