Hi @IniobongNkanga-8038,
Regarding your question, I have a couple of things I'd like you to confirm:
1.Based on your picture, I see that there is only one more administrator for your One Drive. Are you hoping to remove that person as well? Each user is an administrator of their One Drive site collection, and if you remove this sole remaining administrator, that One Drive site collection will not be accessible.
2.Or do you wish to delete or modify the current administrator? If so, you will need to add the new administrator and simply click the fork after the name to remove an administrator.
3.Or maybe you want to stop sharing all the files in OneDrive that are being shared?
We would appreciate it if you would like to share an update on your problem. We will help you solve the problem together.
