Manual or quicksave always brings up error message LoadSave_MB_NotEnoughDiskSpace even though there is more than enough space as requried. I've tried giving exception to Malwarebytes and always run as admin but still the same error message. Thanks for any help in advance.
Found the solution to this problem on windows 10 pro

Go into settings and then windows security, select Virus and threat protection then on Virus & threat protection settings click Manage settings. Locate Controled folder access and click Manage Controlled folder access then click on Allow an app through Controlled folder access where you then can add the game folder which will stop the save function being blocked.
