If unlucky, Maybe You need a clean install. For this:
- Uninstall Unity.
- Find and delete Unity folders in Program FIles (x64, x86) , Program Data, C:/Users/“Username”/AppData(hidden)/ (Local, LocalRow, Roaming)
- Clean System with something like ccleaner.
- Reboot.
- If not helped, try to contact Unity Support.
Or Maybe this is a Windows 10 incompatibility issue. Try to install Windows 7/8.
