Sims 4 running high memory in task manager

@HextraHunt  Sims 4 itself is only using 32% of your CPU and 2 GB memory, both of which are perfectly normal.  The question is what else is eating CPU and RAM.  To find out, you can click on one of the headers to sort the list of processes by use of that resource, so you'll be able to see what else is requiring the extra power.  Let me know what you find.

You can also try setting the EA App to run in offline mode.  This will cut off your access to the Gallery but won't otherwise affect Sims 4, and it's a useful test even if not a long-term solution.
