GDrive Account Can't Deleted

Hi I setup gDrive backup with name = zerodev (backup)
However, when I click the account, it display

Data supplied is not accepted, following characters are not allowed in the input ` $ & ( ) [ ] { } ; : ‘ < >.

How to remove that account?

This account can not be removed for now because of input used in the name, you can continue setting up a new account.
