IIRC GDPR only applies if you are operating a business or organization.

Depending on how this project is structured, it wouldn’t have to process your GDPR request.

Edit: I was only partially correct. According to Article 2, Point 2C, the regulation (GDPR) does not apply to the processing of personal data “ by a natural person in the course of a purely personal or household activity”

So if this project can be viewed as a personal project (which I suppose it could, in theory…), then it wouldn’t have to comply.
