If none of those help, please create a new admin user account on your computer and try playing in that. The username should contain only letters and numbers, no special characters or accents. Make it a local account, as in, don't sign into Microsoft, and don't sync with any other services you normally use. You'll be able to login to your existing Origin account and shouldn't need to redownload anything, but your saves and other user content won't be available.
