[CURRENT ISSUE 64-bit] Keyboard commands don't release

So. Every time I try to change anything on a lot, all my changes get reverted back to how they were before I started editing the lot. It's like someone said "revert" (like when you edit a photo on and there is a "revert back to the original" and your edits go away). I am so irritated because I just wanna play my favorite game and build houses like I used to. 

ANYWAY... I can assure you that this is not a keyboard issue or has anything to do with the functionality of my computer as I am typing my frustration. 

I have also done the following:

1. Uninstalled and reinstalled the game
2. Deleted the Sims 3 folder
3. Played with and without mods
4. Uninstalled my CC and redownloaded and reinstalled ALL of it 
5. I have tried to get in contact with EA and they just closed the issue. FYI EA: It is still happening! 
6. I have turned my computer on and off
7. I have repaired the game via origin.

I have not (yet) given up hope and downgraded my old computer to Mojave because 1) Sims 4 is nowhere near as good as the Sims 3; 2) I just want to play my game that I have invested not just my $$ but days of my life (the simhole).

For reference my computer specs are 

• MacBook Pro 13" 2020

• 2.3 GHz Quad-Core Intel Core i7

• 16 GB 3733 MHz LPDDR4X
