What to try next for installation?

I just remembered that one of the Qubes OS developers is releasing a weekly build, which includes a newer kernel than the 4.1-rc1 and rc2 build. New hardware requires a new kernel.

So, could you try to download Qubes-20211120-kernel-latest-x86_64.iso from the following link and test it?
