Sims 4 freezes leaving build mode/red border/can't click

@IzzyPlays1  I've moved your post to the Sims 4 PC tech section.

Both of these issues are most often caused by the UI Cheats mod.  Try removing it.  If that doesn't help, remove all your mods and test.  If the problem is gone, you can add them back in batches, testing each time.  Any batch that reintroduces the issue needs to be split and retested until you find the probelm file(s).
