Govee M1 with Matter will not connect. Other options?

So I’ve consulted forums and Google in general with no luck. The light shows as an eligible device on HomeKit but never gets past connecting/setting up screen.

I reset it a thousand times and power-cycled, tried adding to wifi with only 2.4Ghz band, made sure IPv6 is enabled on my network, tried adding from HomeKit first before Govee app, then tried adding to Govee first before adding to HomeKit.

I also scanned the QR code on the device and the one shown in the app, as well as also just manually entering the code.

I have the Govee Star Light projector and was able to set it up, so I’m not sure why this won’t work. I could set up HomeBridge, but would rather do something easier if there’s anything else I can try.
