That could be the issue, you see the 64bit version of the game has an issue with the latest Windows 10 updates, I had this issue in May, the simple version of the fix is to run the 32bit version of the game. The only difference is how fast saves/the game loads, nothing else. There are two ways to do it, messing with the coding (which is what is recommended by most) or deleting a folder in the folders.
The newest/deleting the folder (which is more simple and gets the same results) is all the way at the bottom of replies and should be just before that the coding way. There’s something within the 64bit version of the game that conflicts with windows 10.
Both ways are on my old thread here:
