steam not opening properly?

when i go to open steam, i am met with nothing but a black screen.

i can still click on things and use it but i can only see black. sometimes it glitches and i can see what is actually on there for a split second but🤷🤷.

i've tried googling whats wrong with it but everything just says to clear the cache which i can't do since i can't actually see my screen to find it.

any info is greatly appreciated, thank u :)
