According to my browser history, I downloaded this:

https://download.opensuse.org/distribution/leap/15.5/iso/openSUSE-Leap-15.5-DVD-x86_64-Build491.1-Media.iso

I downloaded the checksum and verified it. I then burned it to a DVD and booted
from that. I selected "upgrade," and it didn't work.

The upgrade DVD didn't detect my static IP configuration. That's fine; I was
able to continue using a temporary DHCP address. I don't think that's related
to the problem.

But the upgrade itself failed. The "next" button does nothing at all. It just
freezes there.

I'm willing to poke around to try to give you more information than just the
error logs, but I'll need something more explicit about what you need. (And how
to get it.)

The system was originally installed (from scratch) with OpenSUSE Leap 15.4. The
packages have been updated consistently, but this is the first time I've tried
upgrading to a new release.

I can't really reinstall it, as it's a pretty important system. If you can wait
a few years, I can probably build a new system to try out something different.
Otherwise, I'm either marooned on 15.4 or I'm going to have to try the
(apparently riskier) live upgrade mechanism.

I was hoping that DVD-based upgrade would be more robust.
