My gmod main menu screen is all white

when ever I open my Gmod and it goes to the main menu as soon as it gets there the screen goes blank and I tried deleting the backround knowing Gmod would automaticlly fix the problem and it didnt an some of the options in the main menu dont work like “Singleplayer” doesnt work and this all started when the new gmod update happened can anybidy help me fix this problem?

I got all excited when I saw this link on google, becuase I have the same problem.

Is there a fix?

Ummm… try installing a new background from gmod.org and post your pc’s specifications
