Why do not want to share your detailed system info and logs related to unsucessful boot ups? Where to obtain them is mentioned by the link in the Unable to run Manjaro Linux with kernel greater than 4.14 - #3 by ChrisCanyon post.
Why do not want to try an alternative way of trying to bootup LiveCDs powered by 5.15, 5.10, 5.4 (Manjaro 21.2.0 Qonos released!) and to mention were they able to boot up or not?
