The problem has been solved. It was due to a lack of memory in my onedrive. This prevented complete synchronisation with sims 4.
The risk is to have another problem when my onedrive is full.
How can I anticipate this problem?
@celinette1976 You could get rid of OneDrive, or you could keep it but prevent it from syncing Sims 4 content. For the latter, you could still manually upload your backup saves or whatever data you want to protect; the idea is that OneDrive wouldn't upload anything on its own.
The first post on page one of this thread has instructions for how to implement either of these options.
