I'm also locked out as well.
I was able to play one game where I needed to cut down 8 trees in 60 seconds and after failing miserably at that (only managed to cut down 5), I went to try again and had a different mission to cut down 60 shrubs in 60 seconds, and then the locked out popup appeared right as the game start timer countdown hit zero.
Is this just a lockout for a day or something or is it permanent? I'm using the latest Chrome on an M1 Mac Studio if it helps at all.
