How can I hide map in the corner?

Looks like an error is keeping the minimap module from loading properly.

Turn on LUA errors with '/console scriptErrors 1'
Once errors are on you can /reload and see if any errors popup
If you get more than 1 error i would recommend installing Bugsack and Bug grabber.
BugSack - https://www.curseforge.com/wow/addons/bugsack
BugGrabber - https://www.curseforge.com/wow/addons/bug-grabber
These will put the errors into a bag icon on your minimap and make them less annoying.

I've got the same problem. Here are the Errors I'm being thrown when I have the Minimap module enabled:
