You have a large repo whose size is GBs. Then you may have some issues when cloning it to your local. You can use the following command to clone your project with a small part of your git history;
git clone --depth=1 <remote_url>

Once you have cloned your repo, you can complete your history by doing;
git fetch --unshallow
or
git fetch --depth=<an integer value that shows number of commits>
if it doesn't work with a big value, then try a small value and keep increasing it as each command completes fetching
