For anyone looking for a quick fix to make your site working again you can rollback the tutor lms version back to the 2.77. I did it immediately as i saw that the 3.0 was not working.
Here is a link to a video that shows how to go back to the 2.77 version in case you need it.

I’m also having the same issue. I see the message “Failed to initialize plugin: codesample” whit no context.
