I had a problem with the fontloader and luatex. I tried to run my test document with context (latest minimal) to compare the output, but I failed.
The font LibertinusKeyboard-Regular.otf https://ctan.org/tex-archive/fonts/libertinus-fonts/ uses ligatures especially for the keys above 0xFFFF However, I cannot get it run with latest mkiv. It is no problem with xetex. It should print only the five keys and not the ones for every single letter.
