There has been a critical error on this website

I got the message above today and contacted my hosting company, they sent me the following details;

The error log specifically mentions a plugin - Brizy.

I've disabled Brizy, which gets rid of the error, but the website does not appear to function correctly without it.
Here's the error log for reference.
