Could you please tell us where did you buy the license of OneDrive or other Office products includes OneDrive? Is the domain name "onedrive5tb.com" registered by you?
Before this problem appeared, was there any banner appears at the top of the OneDrive for Business site?
Please locate to Subscriptions, then login into the account (username@onedrive5tb.com) to take a screenshot of licenses.
I understand the mood of not being able to access files on OneDrive, but Q&A forum focus more on general issues, as your issue is urgent, I suggest you let the administrator to contact Microsoft directly to seek help.
Thanks for your understanding.

Do users have the accounts that use domain: onedrive5tb.com?
If yes, for further analysis, did the school organization buy this domain name?
Based on this article "Office 365 Education Self-Sign up: Technical FAQ", Office 365 Education provides self-service sign up for your students, faculty, and staff using their school email addresses.
Because this issue is urgent, it's better submit a service request directly to Microsoft to seek help. Here is a global Customer Service phone numbers.
Thanks for your understanding.
