Have also a strange [never before in decade] install problem with 42.1; after download, burn and verify, and start of install [got screen where select ‘installation’] and see that it has finished loading the Linux kernel, it goes to black & white scrolling script and then ends [cursor blinking at bottom of screen]; no further screen or install progress.
First time it ended at line : ‘[0.253117] PCI:using config type 1 for bass access’
After that first time it stalled 3 times in row at: ‘[0.44494] Timer: vector = 0x38 apic=0 pin1=2 apic2=-1 pin2=-1’
Should mention that initial laptop [Itronix VR2] b&w [not LEAP OS] screen has: 1. Legacy (isolinux) Select CD-ROM Boot type: (put in the 1 and Enter and starts install process).

Installing on General Dynamics GoBook VR2 [Intel Centrino duo]

Would it help to input various kernel options?

You have to buy Suse Leap 42.1.
