Can't make changes to build

Hey, I've gained an issue today that I have never seen before. When I open my save (which happens with no problems) I instantly click on build mode because I'm trying to extend my house. Once in build mode it allows me to place a couple of floors, however after 3-5 actions when I try to extend the platform it just doesn't work even though everything is within the limits and has a green outline. Furthermore, when I try to delete the floor I have just placed it makes the sound but nothing happens. I tried to sledgehammer other parts of the house, but again nothing got deleted. Once I went back to live mode, my mouse moved but it would not let me click on anything and when I made the game play, time was frozen and none of my sims moved. The options menu still works but when I try to exit the game nothing happens and I have to force quit (this is for both save and exit and just exit). I have cleared my cache, repaired the game in the ea app and still doesn't work. Anyone else with the same issue? (no mods or cc)
