"The Great Reset" is the name of a book by Klaus Schwab, who is chairman of the WEF. It was also the name that the WEF gave to their 50th annual meeting, which took place in 2020.

Conspiracy theories aside, I've read Schwab's book, and it's a moronic, badly-written pile of buzzwords and corporate jargon that says nothing of interest and reads like the work of a hungover undergraduate who's padding the wordcount the night before the deadline while hoping the professor won't realise he hasn't done the reading. I'd tell you to ignore it, except Schwab is a man of enormous power and influence, so his apparent inability to produce an intelligent thought is really quite troubling.
