Error with the system.Data.dll of the editor with that of the project

I have the following situation, I am migrating a project that I have done in unity3d 5.6.7 to unity 2018.4.5f1. The project is imported to me without problem, it does not send me any error, during the import the problem precedes me later when it opens in the console it sends me an error that tells me that the system.Data.dll is duplicated if I proceed to remove it from my project the error is eliminated but the sqlite I am using does not work for me. Then I leave the error you send me to see if you can help me.

Thank you.
