Sometimes pushing to or pulling from a branch gets stuck indefinitely

**Describe the bug**
Occasionally, when I push local changes to a branch, or pull/fast-forward, lazygit displays the "Pushing..."/"Fetching and fast-forwarding..." indefinitely.

The command log shows the requested task in yellow colour, but it doesn't show any actual git command being performed (see attached screenshot below).

**To Reproduce**

I'm afraid I don't have any specific reproduction steps. I may be performing a specific task in lazygit casually that is the cause of this bug, but I can't think of anything relevant off the top of my head.

**Screenshots**


(notice it says "Fast forward branch" but there's no git command below that)

**Version info:**

```
~/Projects
❯ lazygit --version
commit=, build date=, build source=homebrew, version=0.40.2, os=darwin, arch=arm64, git version=2.39.3 (Apple Git-145)

~/Projects
❯ git --version
git version 2.39.3 (Apple Git-145)
```

In the mean time, I'll try a manual build of lazygit and assess whether I can still reproduce the bug there.
