Fail to boot into Live USB with RX5700 XT

Hi,
I'm trying to install Manjaro XFCE 20.0.3 from a live USB, but the boot either freezes or hangs before reaching the XFCE desktop.
Running without the nomodeset option, the boot freezes in the following state:
IMG_20200613_234639
The computer is frozen and CTRL+ALT+F6 has no effect.

Running with the nomodeset option, the boot does not freeze on the previous stage but hangs in the following state:
IMG_20200613_234355
I can access the console with CTRL+ALT+F6.

This is the output of inxi -Fxxx:

The Live USB drive is working properly, I used it to boot another machine without issues.
I have found several people with issues with the RX5700 XT, but they are all from last year, so I'm not sure if there was no progress or this is a different issue.
Is there anything I can do?
Thanks for the attention.

choose only free drivers , no change boot kernel parameters to do
maybe "iommu=pt" to add
retry !

Tried with both free and nonfree drivers.
"iommu=pt" had no effect, unfortunately. Same results as previous attempts.

Maybe some experienced forum members can help you to get this pretty new device running. Otherwise, I have a plan B for you: Install Ubuntu, which is already supported by AMD for the RX 5700 XT, directly:

Just in case it's useful, here's the Xorg.0.log when I try to run sudo startx. By the way, explicitly setting X.modeset=0 makes no difference:
