We are very sorry that you feel this way. We do really want to help.
Reset of theme options to default settings usually happens because of the DB manipulations. So, we recommend doing Theme Options backup (Theme Options > Import/Export > download export file to a safe place) and use this in case you face reset.
Images were physically missing on the path that was used in the DB, it’s not related to the theme but to your WP and DB. So, if you upload images to correct folders depending on the path you have for the missing files in the console you’ll get them back. Unfortunately, I can’t check your site now because you changed access.
Also, you can try to make backups using the Duplicator plugin. It makes a copy of the site correctly and allows you to restore the copy without such errors.
Let me know if I could help you with anything else.
