Hello,
Sorry it is a late reply I have been trying to fix it since and remembered this forum. When I open the reliability monitor there is nothing shown as an error from times I have opened sims. I opened sims about 3-4 hours ago, and again at the time of this reply and there is no errors on Reliability monitor for the last 2 weeks (Which are not from sims). It does not "crash" really. The game gets stuck after clicking the check mark after creating a sim. I can get into the game fine through the scenarios with pre set sims but the second I go into CAS it won't get past the part where I click the check. The sim idles in the background and it stays that way until I eventually give up and force close Sims 4.
