Cannot install Fedora Silverblue - the installer crashes immediately after displaying the language prompt


I am trying to install Fedora Silverblue 31 on a new PC. I have previously installed it on a tablet with no trouble, using the same installation media.

The new PC is using an X570 chipset, with a 3900X CPU, along with Radeon RX 5700 XT and Radeon RX 550 graphics cards.

The installation media gets tested first for correctness, and passes fine. I see a text log with various start-up messages. I then see the Fedora GUI installer appear with the language prompt - it shows for about a second, and then the screen blacks out with the log message “terminated” appearing. The PC then restarts.

What’s going on here? Thanks.
