Is your file in Basic Rules normal?
This way there are no error messages.
1) On the other hand, as there is no winner at the moment, your Super Cup will have to be postponed to start in 2024. To do this, you'll have to switch to Advanced Rules.
2) Another problem you'll undoubtedly encounter is the risk of having teams qualified in other continental competitions appear in your CWC.
For this kind of file, I think you'll have to switch to Advanced Rules in any case.
Edit: Your schedule is pretty tight too, in the group phase you have 7 games in less than a month.
Then for the elimination rounds in 12 days you have 5 matches, which can also cause scheduling conflicts.
