@trewlady Has the mouse pointer issue just started this year? Various consoles have had problems with this since the January update, Patch 1.69 and we've made the team aware of it.
There's a thread here just solely for controller issues where feedback is being taken by EA:
https://answers.ea.com/t5/Technical-Issues-Consoles/The-Sims-4-on-Console-Feedback-Thread/m-p/12700067So that's the place to mention your pointer problem. I've had that as well and just as you say, it requires shutting down the game to get it back.
I found another Solved post about ps4 lag with another tip to try here that involves bringing up the inventory to clear the lag, see the last post:
https://answers.ea.com/t5/Technical-Issues-Consoles/Sims-4-on-ps4-is-always-lagging/m-p/11887637#M17541If that tip doesn't help, what I would do is make a post on this thread:
https://answers.ea.com/t5/Technical-Issues-Consoles/bd-p/the-sims-4-technical-issues-consoles-enJust like you've done here, it should get a reply for you. Give as much technical info as you can about your console. There are bug reports about lagging at specific times so it may result in a bug report. You should get a response there anyway.
A few more tips, check your Sim total. In Game Options it will show your maximum allowed. Check you're not near or over your limit. Move some Sims over to Other Households to free up space. Check your library isn't extremely full and trim it down if it is and do the same with Other Households. I've found that clearing all the Library content that arrives with updates and new content can help. Those pre made houses and Sims I don't intend to use just take up space. I usually keep Other Households under about 100 or I find my game becomes unstable. I cull extraneous NPCs about once a week because I put my extra households there so I don't need hundreds of Townies too. Also, if you have a few previous households go back through them and clear their personal and household/ build inventories and always clear inventories before switching households. This includes emptying fridges too. Carrying multiple inventories can cause lags and crashes.
But with the seriousness of the problem for you, another option is a help call with your manufacturer. I've had to do this before but have only tried it with Microsoft. It was actually really helpful for me.
I hope something here helps. Good luck!
