I have an HP U28 monitor, purchased about a year ago, that I connect to a Macbook Pro 14" (M1) via USB-C (Thunderbolt) cable. Most of the time it works fine. But periodically, when I plug the cable into the laptop, nothing happens—it acts as if
there's no cable connected. This has happened since I bought the monitor, but seems to be getting more frequent.
The only way I know how to fix it is to unplug the monitor and plug it back in. That always resolves it. Other typical methods have no effect: unplugging and replugging the USB-C cable, rebooting the laptop, turning the monitor off and back on...those never fix it, while unplugging the monitor does.
Any idea what's going on here?

Welcome to the HP Support Community
I understand you are facing an issue with your HP U28 4K HDR Monitor. Not to worry I will help you to get a resolution to resolve the issue.
Please update the MAC OS once then try connecting it to your MAC PC.
If it still fails then try updating the printer firmware: Software and drivers for HP U28 4K HDR Monitor
I hope this helps! Keep me posted.

There are apparently no Mac drivers for the U28. I called support about this issue and they were no help. They said it was a hardware issue and wanted to connect me to their PAID software support to evaluate my MacBook settings. No thanks! Very disappointing !

My macOS is up to date. When I go to the Software and Drivers link you provided, the only option I see is to download the HP Support Assistant for Windows. (See attached.) That's not really doable on a Mac (since it's Windows-only) so to make that happen I'd have to find an old computer, install Windows on it, and connect it to the monitor—a lot of work if we don't even know whether the firmware needs an upgrade.
My current firmware version is 0.0.1.10, hardware revision IIM111. Can you verify whether that's the latest firmware? If not I will try to upgrade somehow.
