Text tool is not working

Hi All, 

I have seen many similar issue than mine on the forum but still couldn’t find a solution, so if somebody could help me that would be great! 

I have an issue with the Text tool, every time I select it and try to write something, either blue dot lines appear (and only in the corner up) -- see screenshot 1, or the text box appears and empty (and impossible to write something in it, I don’t even have the text cursor only the selective arrow) -- see screenshot 2.
