I've been having a problem with this in my game, too.
The DIY Garage doors from City Living are also causing an infinite loading screen for me if I try loading into a lot that has them. I've had several lots break because of this item, but I was able to save the lots by disabling City Living through the EA App and then loading into the homes and save them without the garage doors. This only started happening to me after the Crystal Creations update though.
I can give you examples of the lots causing this issue for me. Simlicy's Brindleton Family Home, Simlicy's Modern Copperdale, Simlicy's Vanessa Jeong's House, SimmarySims Cozy Family Home. These were the lots in my game causing the infinite loading screen because of the DIY Garage Doors. They were working just fine before the recent patches.
The DIY Garage doors also disappear for me when I try placing them, but knowing they cause the infinite loading glitch for me I don't even bother trying to use them anymore.
