Accidentally excluded all studies, removing previous screening progress

I was screening all my papers using different filters (in the new interface), and I accidentally selected all studies and clicked exclude (it asked me to confirm and I pressed yes, but I thought it will only exclude the filtered ones). Now all the studies (1900+) are excluded, and I've lost all progress on the "maybe"s and "included"s. Is there a way to undo my action? Please help as I had spent a lot of time and effort. Thank you
