Game not responding past introduction loading screen?

Hello
Try moving your whole mods folder to the desktop. Delete the cache files
https://sims4.crinrict.com/en/2014/09/delete-cache-files/
Then start the game and test to see if that helps the issues. If it does help, then put your mods/CC back into the newly generated mods folder in the sims 4 folder one by one or in batches and testing the game after each one to see which is the cause of the problem. Put one item or batch in , test the game , take it out. Then test another one, to find the cause of the issue.
