@CrookedTail_19 For this issue you need to move the Sims 4 folder to the desktop from Documents > Electronic Arts then attempt to launch the game so a new one is created.
If it launches ok then copy your saves from the Sims 4 folder you moved to the desktop, into the new Sims 4 > saves folder in Documents > Electronic Arts. Copy the actual save files, don't move over the saves folder.
If you have multiple saves you should copy them individually and test the game loads after adding each one. No need to copy over the save files ending in .ver0, .ver1 etc. as these are backups. Just copy the ones ending .save.
