Trouble updating firmware on Ender 3 V2 4.2.2 (GD32F303)

I recently tried updating the stock firmware on my Ender 3 V2 4.2.2 GD32F303 to the latest Marlin-bugfix. Unfortunately, after doing this, the printer freezes on the boot screen.

I’ve since tried to reinstall the stock GD-Ender-3 V2-Marlin2.0.8.2-HW-V4.2.2-SW-V1.0.4_E_N_20211230 from the Creality Support Page, and renaming the file firmware-1.bin, but the printer still gets stuck on the boot screen. I’ve also tried using a different 32GB SD card to no effect.

Any suggestions for other troubleshooting steps I might try?
