Wont finish building

[aaibng]

Hello,

I was using Binder for a school project and is now stuck. Two days ago it would build and I could launch. However now it does not finish building, it reaches the last stage 11/11: registering template.

It doesnt move on from here. And my previous build wont launch at all.
The files it was building on only had internal jupyter notebook changes, enviroment and overall architecture is still the same as it was when it would build.
