I am sorry that you are having game issues
If you have cc/mods in your game, move your whole mods folder to the desktop.
Delete the cache files
Then start the game and see if the issues are still there. If it has helped with the issues, put your mods/ CC back into the newly generated mods folder that is in the sims 4 folder one by one or in batches and testing after each one to see which is the causes of the problem.
