LazyGit crashes, when opened in a TMUX-Pane with wrong `default-terminal`

[Rocco-Gossmann]

Describe the bug
I've had an spelling mistake in my TMUX-config.

-set -g default-terminal tmux-256colop
should be
-set -g default-terminal tmux-256color

For some reason, the spelling mistake prevented Lazygit from starting, when opened in a new Pane or Window.

tmux split-pane 'lazygit || bash'

Lazygit is the only TUI application that crashed, because of this.

To Reproduce

1. Install tmux and lazygit.
2. Create a .tmux.conf file in your $HOME directory.
3. Open the .tmux.conf file and write -set -g default-terminal tmux-256colop.
4. Save and exit the file.
5. Run the tmux command.
6. Now, from within TMUX try to open lazygit via the following command.

tmux split-pane 'lazygit || bash'

Expected behavior
To not crash.

Version info:
Lazygit - Version

commit=, build date=, build source=Homebrew, version=0.50.0, os=darwin, arch=arm64, git version=2.39.5 (Apple Git-154)

Git - Version:

git version 2.39.5 (Apple Git-154)

TMUX - Version:

tmux 3.5a

Additional context
Setting the default-terminal to tmux-256color fixes the issue, but as said above, Lazygit is the only application, i've encountered, that creashes because of that spelling mistake.
