The sims 4 Cannot start because of missing or damaged data

I'm having the exact same problem, except when i do try to create a backup as instructed in the link (on my USB). I still get the error when I try to start up the sims 4. I save the sims 4 folder from documents into my USB and then I name the folder in my documens "The Sims 4_Backup" but I still get the same error, please help ☹️
