GMKtec EVO-X2 minipc, graphical installer error

I recently picked up a GMK EVO-X2 minipc with the new AMD Ryzen AI Max+ 395 chipset. I’m trying to install NixOS on it, but the LiveUSB graphical installer (created with dd) fails with the following error:

The minimal installer loads with no problem, this only occurs with the graphical one. Anyone know what might be the problem, or suggestions for troubleshooting it?
