UE4项目提交大量文件Push失败求助：RPC failed等错误

I'm trying to push a major update for my UE4 project to GitHub—this commit includes tons of modified and new files, but I keep hitting these errors:

fatal: the remote hung up unexpectedly.
error RPC failed; curl 55 send failure: Connection was aborted.

Weirdly, my local Git says Everything up-to-date, but the remote repo hasn't received any of these changes. This work represents weeks of progress since my last commit, so making sure none of it gets lost is my top priority.

I already tried increasing the upload post buffer size with this command:

git config --global http.postBuffer 524288000

But it didn't fix the issue.

I have two main questions:

• Would uploading the entire update as a new repository or a new branch work? Are there any downsides to this approach?
• Is there a better solution that lets me fix the push issue directly, without having to create a new repo/branch?

This is my first time posting on Stack Overflow—any help or advice would be really appreciated!
