Re: Sims 4 unable to start
@TJmorris23
1. Open windows task manager (ctrl+shift+esc) and see if there are any Sims 4 process running on the background (check the process tab), and finish them. then start the game again.
2. The reason can also be your Windows Defender like here - you must add TS4 to the exception in it

How to add TS4 to exceptions in Windows Defender
Open Windows Defender
Click Virus & Threat protection
Click Virus & Threat protection settings
Scroll down to controlled folder access
You will see "Turn off"
But you don't want to turn it off so :
Click Allow an app through controlled folder access
Click Add an allowed app
Browse to your Program Files(x86) Origin games\The sims 4\game\bin folder
select TS4.exe click "open"
if you're running 64 bit
select also TS4_x64.exe click "open"
So on 64 bit Windows, you will add both.
Startup origin and try running the game again.
