Highly not recommended to install via an old installer, as configs have changed a lot.
I would recommend you to try using manjaro-architect… but the Manjaro team no longer releases the manjaro-architect ISO unfortunately, which makes me sad because that’s the ISO I mainly use. But it’s probably because it’s unmaintained now. It does get some updates though.
You could technically use it on the Live ISO… but you’d have to update that whole Live ISO to get the newest manjaro-architect because just updating manjaro-architect might break it due to partial upgrade and I don’t think that’ll work that well.
Edit: Oh also, the older ISO might be working because it contains the correct driver for your GPU, and the newer doesn’t by default. It’s a possibility. I wouldn’t know how to fix the issue though… I stick with AMD because it’s built into the kernel.
