In a truly dynamic environment there should be more opportunity to figure out where you can best contribute as a team member. (Work is about more than simple technology.)
Maybe you're blocked in some areas, but are there others where you can help with your unique combination of knowledge and experience?
It doesn't even have to be directed at the core of the project. Some teams aren't good at creating infrastructure; maybe there's a need in the areas of documentation, devops, or bug tracking and fixing. Stuff others don't want to touch.
Consider starting there. (And always be thinking about your next move.)
