How do I get SQLite databases working in my build when they already work in my project?

Today I was supposed to begin testing my build, but I've found that I've done something wrong with SQLite integration and I'm not sure what that is.

Everything works in the unity editor, but I think I've missed a step to allow the databases to be created properly in the build folder. The core game systems rely on the databases working correctly, and they are not.

There is a lot of code in my project, so I'm not sure what to share, so here is my Database Manager script, and a screenshot of my project setup.

I think there is something wrong with the location of the databases or how they are being handled in the build, but I have no idea how to fix this type of issue.

Thanks in advance for any help. I am happy to provide any additional information you may need.
