Wordpress debugging

Our Wordpress theme randomly caused the site to be corrupted. We only notice when we received the email message below. We were able to log in through recovery and switched the Theme, we would like someone to debug the theme so we can activate it again. We appreciate real bids and not automated bids. Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email. In this case, WordPress caught an error with your theme, YOOtheme. First, visit your website ([login to view URL]) and check for any visible issues. Next, visit the page where the error was caught ([login to view URL]) and check for any visible issues. Please contact your host for assistance with investigating this issue further. If your site appears broken and you can't access your dashboard normally, WordPress now has a special "recovery mode". This lets you safely login to your dashboard and investigate further.
