Hi Hans,
I am not a font specialist and I use pagella and modern.
I'm curious so I installed this new font in
/home/viserion/LMTX/tex/texmf/fonts/opentype/public/newcomputermodern
I tested your file and I get the following message
Thank you Fabrice

Sorry, but I can't typeset math unless various parameters have been set.
This is
normally done by loading special math fonts into the math family slots.
Your font
set is lacking at least the parameter mentioned earlier.
