Try this:

Is there any chance of losing the users mailbox or one drive data during this process
Its also worth checking if the users onedrive data got restored after you re enabled the user. Do you get any correlation ID error when you click the mail tab of this user in the M365 admin center?
Yes onedrive data is also there and no correlation errors for this account,
They are able to login from mobile but from web it's not working
