Hi Heather,
This is a layout change, not a removal. Office.com now takes you to the new Microsoft 365 home and the Admin entry can get unpinned.
To bring it back, sign in at microsoft365.com with your admin account, open the app launcher or the Apps button on the left, choose All apps, find Admin, open its three dot menu, pick Pin to launcher, then refresh the page. The Admin menu should reappear for you on the left rail and in the launcher.
