Repository Data Quota exceeded (Unreal Engine 4 connected via Source Control)

For my Game Dev module at Uni, my team and I set up a Github repository (using Git Desktop, Bash and LFS) in order to share our files. After an ardurous and painful set up process, we thought we had everything working fine. We were wrong. Yesterday, during a merge, Git only did half a merge, leaving my version of the project an unusable mess. Today I tried to reclone the project to a new directory so that I could continue with the work I needed to do. The cloning completed suspicously quickly. Only the folders the assets and blueprints were stored in where cloned, none of the files themselves. I decided to try again and actually look at the popup this time. It told me the repository is over its data quota and gave me the following error log.

Can someone help me please as the project has already been derailed and slowed enough (due to over factors beyond our control) and we really cannot afford any more delays. Thanks.

Thanks for reaching out. You can find information on Git LFS data quotas in our help documentation. Let us know if you have any questions.
