Same bug here. Its very annoying. I hope it will fix.
Edit: I've found a new option in Preferences ('User Interfaces' tab, 'Map' section): Exterior Map Default to World Map. If it unset it, map is working fine again.
I have same problem for two days. Tried several thingies (eg. compatibility mode, start as admin), but its still not starting or crashing without error codes. Please fix it, we're running out from current event.
