Can’t access WordPress admin critical error

Hi all! My website randomly went down and has been down for several days, but I can’t get in to fix the issue. I believe it is due to a plugin that caused the error to make the website go offline, but I’m not sure how to fix it because in the past I’ve still been able to login to the WordPress admin side and disable plugins one-by-one until i found the culprit.

I think i know which plugin caused the error because I received a email saying it failed to update and could have caused an error. But upon trying to login to admin all i see is ‘this website has had a critical error’.

What can I do to regain access to my WordPress admin side so i can deactivate the plugin that broke my website?
