I’m a student looking to contribute to an open-source project via GitHub. I’m finding it difficult to locate a suitable project for contribution. Could anyone offer assistance?

The project should consist of at least 15,000 lines of code and have been updated within the last 2 months. This is my first year of programming, and it’s also my first time contributing to an open-source project, so I’m not very experienced. Maybe someone can help me finding a project.

I searched on github on the page issues, but most of the issues are very hard(in my imagination).
