Snowrunner on PC and Epic Games Store. DAT files in My Games path.

My settings are very often set back to the defaults. My wheel has all settings set manually (Moza Racing R3), so quite a problem. But even simple setting like Music Off (0) are lost. When I open the used_settings.dat I see the settings saved.

I have good internet and wait until cloud save is ready before shuting down my PC.

Any idea?
