Critical Error w/ Avada theme

I installed this plugin?and it created a critical error on my website?https://shannonmcguire.com/. When trying to load the back end, I get this error:?https://snipboard.io/bV6NHr.jpg Turning on debug mode doesn’t display anything – however the URL bar seems to suggest it is putting Avada into a strange update cycle. I remember I had this problem a while back with another website and confirmed that it was indeed interfering with the Avada theme. I’m not positive but I may have had to simply restore my database from a backup to fix the issue.

The only way to make the error go away is to rename the themes via FTP. But as soon as I try to activate the child theme, the error comes back, as if there is an entry in the database that is causing the problem. This is a serious issue and I really don’t want to lose all my work – I haven’t taken a backup of the DB in a while. Please advise.
