[BUG] Deleting a worktree while Fork has it opened crashes the Fork App

Using Fork Version 2.69.0 on macOS M5 Pro

Steps:
* Create a worktree for some repo
* Open the worktree in Fork (via the Worktrees dropdown in Fork)
* From terminal run
```
git worktree prune
git worktree remove [--force] -- <worktree-path>
rm -r <worktree-path> # if it still exists after Git succeeds
```
