New save will not play after dloading lot from gallery

So I made a new build recently, and noticed that after I had saved it to the gallery, that my Sim would just stand out the front of the lot and could have co nversations, but couldn't go anywhere.  I tried various things including debugging, pressing m and coming back, transferring households, deleting and re-downloading the build, deleting any objects I used the TOOL mod to place....and nothing worked.  The best i could do was to get the Sim to go sit in the onsen, but then she would get stuck in the ground after removing the onsen.

Anyway, so I started a completely new save, with a Sim randomised from the gallery, placed the lot, and THIS Sim not only does nothing, but I cannot even get the time to play!  I press any of the play buttons, fast forward or 2 x speed and nothing - time does not move, Sim does not move, nothing works.  I can go into build mode, and come back out, and while in build mode I can build, but I can't use Live mode at all!!

I have never had ANY issues wit my game before, I d not have any CC or mods installed (removed them from the folder), but ever since the most recent update for businesses and hobbies, I've had nothing BUT issues!  I do not own business and hobbies either, so it shouldn't have affected my game.  Is there a way to roll back the update???  I can't play
