I just get a white window after building. I selected the dev tools option but they don't open. I did try running the directory with the index.html file using a normal http server e.g. python's in-built or npx run serve - and that worked.
I'm running on linux-x64. Build succeeds with a 3.9MB file but I just get a white screen. I think something is loaded as if i click randomly on the white screen i can hear the sound effect of clicking on one of main menu buttons.
I also tried it with a plain single index.html file with no dependencies - displaying an h1 tag and some p tags. White screen and no dev tools.
