I can't save anything to my library

If you can't stop this action, unfortunately, you have to leave the game without saving,
If you can stop it, save the game and leave.
Go to the Origin / My games library, Right-click on TS4 and select the "Repair" option. You have to wait until Origin checks all packs.
Maybe you have some outdated CC in this room.
Check these CC and scripts mods if you have them - it's best to move the mods folder to your desktop.
Turn on the game to create a new, empty mods folder and check if a game is working now without mods and CC.
Then copy from desktop your mods and CC and paste it in the new mods folder. First, paste script mods one by one every time checking if you can save this room.
Do the same with CC but if you have a lot of this, try the 50/50 method. ( divide your CC into smaller batches for example 50 pieces in one subfolder and check these subfolders one by one)
