Lazygit crashes on worktree with bare repo

I have a repo that I cloned with

```
git clone --bare git@github.com:example/example.git example
```

And added the main branch as a worktree

```
git worktree add main
```

Now, if I go into the `main` directory and I tree to run lazygit it just crashes after opening for like half a second.
I cannot get the full panic because it also leaves my terminal in a messy state.

Lazygit version: `commit=5e388e21c8ca6aa883dbcbe45c47f6fdd5116815, build date=2023-08-07T14:05:48Z, build source=binaryRelease, version=0.40.2, os=linux, arch=amd64, git version=2.34.1`

(thanks for all the work that went into lazygit, been loving it for a while now)
