This is Fedora 39; all neatly sorted and folded.

Hmmm, unfortunately I'm pretty unfamiliar with Fedora. My advice is to search for others having similar issues with Fedora, libnss3.so, and NWJS (our game engine), and see how others have addressed the issue. Sorry friend!

Ok looks like it might be as simple as

$sudo apt-get install libnss3

I just had the same issue, but if you are on a 64 bit system,
the you need to specify to install de 32 bit version of the library, like so:

$sudo apt-get install libnss3:i386
