Client Freezing my whole computer!

I have windows 10 and this patch(6.5) has made a very odd bug. Whenever I log in everything seems fine but when i go to hit and play choose between normals or ranked it freezes. I have uninstalled and reinstalled I have run it as the administrator, set in in different compatibility modes, opened firewalls etc and nothing has worked tried six times in a row to no avail. Please help me figure this out rito!
