Bizarre Indescript Errors in WordPress Admin in Fresh Install

Sorry to be vague, I’m finding it difficult to describe these particular error messages.

I have just launched my first Trellis install locally on Mac OS Sierra and logged into the admin. I’m getting these errors and they seem entirely unhelpful in debugging:

Can anyone help? Thank you!

I circumvented solving these specific errors by executing vagrant destroy and deleting the directory from my ~/Sites folder completely. In other words: completely starting fresh.

But I would still like to know if anyone can help me understand what I may have missed to get the above result?
