Error code 16 after new windows 11 update.

EDIT: Never mind! I just got the error again! I'm going to keep fiddling. I don't know how I got lucky ten times in a row. 

I finally got it working for me! I've tried so many things with no results but now I have been able to consistently save 10+ times in a row. Hopefully this continues to work and perhaps works for you too!

I had to move the location of where my documents folder stores its files. I've attached screenshots if that's easier to look at. 

1) Right click on the Documents folder and choose "Properties"

2) Click on the "Location" tab

3) Click "Move" and when the window pops up make a new folder somewhere else that you'd like to store your Document files. I chose the root directory of a different drive. I wouldn't recommend choosing anything in Program Files or something like that. 

This will move/store ALL of the files in your documents folder in this new location until you change it to something else. I don't know if this will interfere with other games or anything, but I don't think it will since it's changing the overall default location. 

I am using the EA App and I couldn't find a way to specifically store the Sims 3 saves somewhere else but perhaps there is a way on Origin or Steam. There might also be a way to direct the game to look in a different direction for its saves but I'm unsure how to do that. 

Hopefully this works for you!
