Potty trained 3 1/2 year old stopped pooping in potty

I successfully potty trained my 3 1/2 year old daughter at the end of June and she had been doing amazing with it. A few weeks ago she went through a bout of constipation and after a couple days, finally pooped after we put her to bed (she wears diapers/pull ups to bed as she isn’t night trained yet) Ever since, she has not pooped on the potty. She is at the point that she will hold it until bedtime when we put her in her diaper. Either she will cry for us to come change her after or she will fall asleep and husband or I will go in and change her before we go to bed. This is every single night for the past few weeks.

She is speech delayed and cannot communicate her feelings very well so we don’t know what has changed that all of the sudden she will not go on the potty. She still tells me when she has to go pee or goes straight to the potty herself with no issues. I’m at a loss here! Any advice is appreciated!
