Shortcut Keys Not Working

I load into the game, enter Build Buy Mode all shortcut keys such as E Eyedropper, H Select, K Hammer, G Grid, Ctrl Z Undo will not work. When in Live Mode, all shortcuts are working without any issue. This was first noticed yesterday, 16.09.25, but have not been on for about a week prior. I closed the game and reloaded, but it would not fix. I reset everything to default, didn't not fix it. Eventually, I found what I thought was a fix. Close down game, Documents, Electronic Arts, The Sims 4, Find the file Options.ini, Rename it to Options_backup.ini When you restart the game, Sims 4 makes a new default one. This will restore all Build Mode shortcuts to default. Which it did. Then earlier today 17.09.2025, I logged in again, same issue. I closed the game and reloaded, and after about 5 to 10 mins it just started working as normal again. And, I just tried to play again, not 4 hours later, and the issue has reoccurred. So once again, I closed the game and reloaded, and after about 5 to 10 mins it started working again. I appreciate that the quick fixes are working, but I would appreciate if anybody could let me know if they've have the same issue, found more lasting fixes or know what might have gone wrong in my game?
The only thing I can think of that I did 'differently' on the initial log in, is that before loading the save file and incurring the issue, I re activated Seasons, that was disabled via the in game pack selection tool, and loaded into a NEW save.
