When trying to save a project I get “IOException during serialization”, this seems to happen if I try to save or copy one screen but not any others. The screen has some “month view”'s and a report but not a lot else. There was nothing wrong before upgrading to 7.3 and I am at a loss, I have attached the full error code. ![:scratch:](https://us1.discourse-cdn.com/inductiveautomation/original/1X/76d1620bec252bfac07050c889ff5a91dc8a9c25.gif ":scratch:")
