I am using git to host a LaTeX paper I'm writing on both my desktop and laptop. However, it has recently stopped working on the latter. One morning, I was able to clone and push over SSH just fine, but that same evening, without even touching git in the interim, it stopped working. I write git push and it just hangs indefinitely. It still works just fine on my desktop, but I haven't been able to use git to push changes on my laptop in days.
What hasn't worked:
1. Changing Wi-Fi.
2. Using git push origin main instead (main branch is indeed called "main").
3. Trying to push with my firewall down.
4. Deleting the public key attached to my laptop and then adding it back.
5. Restarting my ssh agent using
killall ssh-agent; eval `ssh-agent`
6. Attempting to enter my github site username and password when pushing over https.
7. Running
git config --global core.askpass "git-gui--askpass"
This is the output of running ssh -vT [email protected]:

What am I missing? What should I try?
Operating system is Debian GNU/Linux forky/sid, and git is version 2.51.0.
git pushtrygit push -v(--verbose).core.askPass. Also converted images of text to text---couldn't post it as text originally without being marked as spam. Runninggit push -vjust hangs again.git push -vjust hangs again." Any output?
