Based on your description, this issue appears to be related to Microsoft's ongoing service incident (Incident ID: MO1550821), which is affecting connectivity to multiple Microsoft 365 services, including Exchange Online, Microsoft Teams, and SharePoint Online.
According to Microsoft's advisory, Microsoft 365 Education features, including Assignments, Reading Progress, and Speaker Progress, may be impacted by this incident. This could explain why your Assignments page keeps reloading and you're unable to upload or submit your files.
The incident is currently classified as Service Degradation, and Microsoft is actively investigating and working to mitigate the issue. However, no estimated time for full service restoration has been provided yet.
