Ok, we'll need to check the log to see what's the problem. On the search bar type %appdata%, then go to the Godot -> app_userdata -> Arma's Quest -> Log. There you'll find a few .txt files, they're named with the date and hour. You can copy and post the content here as a reply to this comment
Hi! Sorry for the radio silence! We think we know what the problem is and unfortunately it's kinda big, so it may take a while to solve. We'll work on it and hopefully it'll be fixed by next week
