I was able to fix it by following these instructions provided by support.
We’ll need to reinstall umbrelOS from a USB stick. Fair warning upfront: this will erase everything on the device, so any apps and data you had won’t be recoverable unless you have a backup. Here are the steps:
On a computer, download the latest umbrelOS USB installer: https://download.umbrel.com/release/latest/umbrelos-amd64-usb-installer.iso
Download and install Balena Etcher on that same computer: https://etcher.balena.io
Plug in a USB stick (at least 4GB, it’ll be erased) and use Balena Etcher to flash the ISO to it.
Once flashed, plug the USB stick into your Umbrel Home and power it on. It’ll boot from the USB and start the installer automatically.
When it’s done, the device will shut itself down. Wait for it to fully power off (LED goes dark), then unplug the USB stick.
Power the Umbrel Home back on. The first boot takes about 5 minutes, then head to umbrel.local in your browser to set it up fresh.
As it states I unfortunately did have to wipe the device to do this but at least it’s working now. I suppose I’ll just be a bit more forward thinking and actually use the backup feature to a separate drive this time.
