I'm also facing the same kind of problem but on FIFA 19. After the opening match, when profile is being created, it says that unable to save personal settings 1. 3 options are there - 1) Retry 2) Cancel 3) Continue without saving and none of the option helps. I proceed with 3). Also there are no files when I go to Settings> Delete. If I go to the settings menu to create a profile there, it says there isn't enough space available to save settings. But the fact is that I have about 100 gb free space on the Local disk C in which the FIFA 19 save files are saved in My Documents folder.
