I am having the same experience.
I created a sticker pack one week and then I was not able to after.
Between these two periods I installed an updated version of XCODE and upgraded the OS.
I'm on:
XCode 13.1 (13A1030d)
Monterrey 12.0.1
What is your systems configuration?
2021-11-03 18:09:23.132166-0500 StickerPackExtension[5754:2679938] [PPT] Error creating the CFMessagePort needed to communicate with PPT.
Interestingly, when trying to run the sticker package project created prior to the updates, that works just fine. I'm thinking something was messed up with the last Xcode update.
