Malodiepluss Your UI breakage is most likely broken UI Cheats Extension. Your inventory is most likely MC Command Center but their could be other causes. See Broken and Updated Mods and CC. And also see the section in How to Use Mods and CC on managing your mods when there's a game update.
Most likely not. İ have disabled all my mods and tried again, regardless, doesnt work. They need to patch up the game again...
Malodiepluss Based on my testing of the mod before it was updated, most likely yes. Go update your mods. See https://forums.ea.com/discussions/the-sims-4-mods-and-custom-content-en/1-118-broken-ui-after-patch-live-mode-menus-etc-/12604623
