why is this happening to me??

hey guys! I have never had issues like this with my royal icing before. I was sick for a week and came back to decorating, and my icing will NOT dry smooth. Ive iced 2 dozen cookies and each one looks like it’s covered in pimples!!

I let my icing sit after coloring, popped the air bubbles, helicoptered it in the bag, the whole nine yards to prevent air bubbles so I am SO confused and SO upset. I’m going to have to scrape these and figure something else out :/
