Regular crashes while lazygit is in the background

I'm not sure what triggers this, but it happens when I'm off in my IDE working away.

Occurring on ef82f394312e6f1c100f5153187d5537d701384f. Started maybe a day or three ago.

Also of note, the error output is quite broken. In a `tmux` session if that means anything
