Project can't load nuget package from referenced project

I'm having this Visual Studio solution, including these projects

• BLL and DAL are netstandard2.0 projects.
• ComputerWinForm is .Net Framework 4.7.2 project.
• BLL references to DAL.
• ComputerWinForm references to BLL and it's the startup project of the solution.

In the DAL, there is System.Data.SQLite package. After restoring all projects and running the solution, I got this error.

It seems like ComputerWinForm project can't load the package although the package is already installed.

How can I solve this problem? Please help and thank you.

What I have done:

• Run Update-Package -reinstall.
• Clear nuget package cache and restore all projects.
