Sorry to hear of the problem you are having.
You can update theme manually using FTP as described in the following pages.
If you succeed to log in to your site then please resave your site permalink settings.
I disabled the plugins on your site using shared FTP details and reactivated only theme required plugins which made your site work fine so it seems one of the disabled plugins caused this issue specially Defender.
You can now enable plugins one by one and see which one is causing this issue.
