How do you run Openfire? Is it running as a service or do you run it manually with a launcher (yellow bulb icon)? Do you use Openfire with a bundled Java (jre folder inside the installation folder) or do you install Java on your Windows 10 yourself? If the latter, what version is installed?
Are you still able to login to Admin Console? If so, what Java is shown there on the first page?
Although you said you haven’t changed anything, but some other app could have updated on your system and blocked these ports for some reason. You can try exiting all other apps and then restarting Openfire and see if that changes anything.
