Unclearable nunit error when installing/uninstalling the Entities package on a new project

Repro steps: 

1. start a new project
2. add the com.unity.entities@1.1.0-pre.3 using the "add project from Git URL" option
3. wait for the package to download and install

Actual Result:

• Console prints:

  error CS0006: Metadata file 'Library/PackageCache/com.unity.ext.nunit@1.0.6/net40/unity-custom/nunit.framework.dll' could not be found
  

• The error is unclearable
• This also happens on the flip side: when uninstalling the Entities package
• The error goes away if you re-open the project.

Environment

• Reproducible with Unity Editor 2022.3.13f1 and Entities package version 1.1.0-pre3
• Not reproducible with Unity Editor 2022.3.13f1 and Entities package version 1.0.16

NOTE: I tested with 2023.2, 2023.3 and 2024.1, and this issue doesn't reproduce in newer versions with newer Entities package versions
