S4S Startup Error

Sorry to bother you, but could someone please help me? My Mac has beens getting Sims 4 Studio error since January and it says to post to the website, but none of the threads were allowing me to post/reply. I updated a while ago and even fully uninstalled and re-installed it, but when it opens it says it can’t find my Sims app. I pick the path and I keep getting this error:
