Unity doesn't open

Recently Unity stopped working for me and i have no idea why. I didn't changed anything on my computer and it used to work just fine before. When i open Unity, my whole PC starts running really really slow but the program never opens.

I followed some solutions i read on the internet, including making an exclusion for unity in Windows Defender and on the Firewall and even reinstalling it and Visual studio twice but nothing seems to work.

Specs:

• OS - Windows 10

• RAM - 16GB

• CPU - I5-6400 2.70GHz

• GPU - GTX960
