SPO site doesnt open in SharePoint Designer 2013

Question

Hello, I have been trying to open our tenant in SharePoint Designer 2013 . All of a sudden, it started throwing error from past 4-5 months. Enable SharePoint Designer customization and other settings have been already done.

Please let me know if anyone has overcome this and any workaround to open the site collection for theme/master page customizations.

Thanks

If you have enable this setting, try below things for troubleshooting your issue(check the results after each step):

1. Added yourself to the "Site collection administrators" group, then check the results.
   Note: Even you have full control, but if you are not a site admin, you will have the access deny issue.
2. Go to your site and click "Edit in SharePoint Designer" in the ribbon. It will prompted you for your credentials, enter it and check the results.
3. Go to Site Permissions > Permission Level in ribbon > Click the permission you belongs to > Ensure Use Remote Interfaces is selected.
