Stuck on "Install configuration for *listname*"

[MaiNeym]

Describe the bug
Immediately when starting the actual installation of a modlist, wabbajack can get stuck on "Install configuration for listname"

Additional Context
I can reproduce the issue by going too quickly.

1. Pick a modlist from the gallery.
2. Before it fully finished loading, select an install folder, and click play to start the installation.

Patience is a virtue. But unfortunately not all users have this patience.
Perhaps the start/play button can be greyed out till the configuration finished loading, or replaced with a loading icon?

Wabbajack Version
