If you are playing Wordle unlimited, there is no option to share as far as I can see. If you are playing regular Wordle you should be able to click the graph icon and see a share button there. It will copy to the clipboard and then you can paste it here.
I play on a PC, laptop and phone. All Chrome based. They all seem to work the same for me. If it still won’t work, then I agree it’s probably some extension blocking it for some obscure reason.
BTW … not sure if I should mention this … 
LOL
But … on Wordle Unlimited you can increase the amount of letters for added fun Just click the settings gear.
