I see this is a rather old thread, but I just found the same crash issue using Feodra 36. Logging into an x11 session fixed the issue, meaning the problem is a wayland/xwayland issue.
While not technically supported, Feodra is more or less the same as CentOS and uses the Gnome desktop. Heck I can even install CentOS packages, so I'm unwilling to blame Fedora for this issue. Is there any log I could provide to help diagnose the issue? Other Unity games and projects run fine under Wayland, but no others I've used have tried to save something to disk.
