i can't type, the box showing unstop !

Hi

I'm the new guy for Adobe Illustrator hope everyone can help me to solve this situation

for now I just in stall the Newest version of AI and try to do some work but every time i try

to type or click somewhere in the Text Mode the box like an unusual font will always show

and unstop as same as my keyboard was broken but it isn't. another problem was i can't click

anything in the tap of UI function such as color UI.

with a hopeful thanks.
