Cannot push Unity project to Github repo

I can’t push my Unity project to Github repository, and no matter what I do, it does not resolve the problem.

Here is the error every time I try to push it:

"Enumerating objects: 3870, done.
Counting objects: 100% (3870/3870), done.
Delta compression using up to 8 threads
Compressing objects: 100% (3869/3869), done.
error: RPC failed; curl 55 Send failure: Connection was aborted

Total 3869 (delta 2407), reused 0 (delta 0), pack-reused 0
fatal: the remote end hung up unexpectedly
Everything up-to-date"

Now from the point of view of someone like me who doesn’t understand technical stuff, this does not make any sense. Any solution to this, please?

It looks like you’re trying to push 1.54GiB of data all at once, which is a lot to chew through. If you can, try to push parts of the project at a time instead of all at once. This might mean undoing your commit or reapplying your work.
