Every time I get this error on the main menu my save is deleted.

I've checked and my save is present prior to launching the game.

I am backing them up after every play session, but it's annoying to have to replace it all the time because this error happens frequently when I launch the game after powering down my system for the night.

In fact, it's never not happened when I launch the game after turning on my PC for the day. It also takes a very long time for the game to launch when this occurs and another long load is present when I go to the main menu.

It is worth pointing out that this is a single user PC, so it's not another account trying to share it that is the issue.

After that, it runs fine, and I am able to paste my backup save into the game and play it, but the initial launch after booting reliably causes this error every time.

I also have to rebind my controls again every time this happens.

I have the Windows Store version.
