Starting yesterday, HA Yellow "hangs" every time I restart it

Yesterday I added a Hue light via Z2MQTT. There was a message that said it needed an update, so I clicked install. It never installed, and when I refreshed the browser, it said it couldn’t access my HA Yellow. (Full system with CM4 preinstalled, not POE.)

I tried rebooting (computer, router, and HA) and using a different browser. I finally gave up and tried to do a factory reset, which also didn’t work.

Today, the factory reset worked and after HA Yellow installed, I set about installing the terminal, HACS, etc. Unfortunately, every time I restart Home Assistant, it becomes unavailable.

It’s not always visible in my router, but when it is, I can ping it. I can’t restore from backup. Is it just hosed?
