I built the game, but when I start the launcher, it tells me to build it and doesn't let me trough. I tried launching the executable on its own and it works perfectly on the title screen (though after selecting a file, there are some missing textures which might be related to an error I got during the building process, but there is already an issue about that: #90 (comment)).
The git repository is cloned into the launcher's folder as it should be.
OS: Linux Mint 22.1
