How to log into a Linux virtual machine when its root user is expired and reason being failed to change password

I created a Ubuntu 18.04.6 LTS VM on vSphere. Created a user, test. VM is a 1-year-old machine. Now when I am trying to log in ( through PuTTY), I can't. I checked the logs it says that the "account root has expired" (failed to change password) and the account test has expired (failed to change password) How can I log in to the VM?
