"npm run build" gives tons of errors

win10, node v18.16.0, npm 9.5.1,
clean clone, npm install followed by "npm run build", tons of errors like these. Did I miss anything?

Given that all the errors are at the end of lines, this looks like a CRLF vs LF issue (although I'm a little surprised the symbol is displaying as a unicode replacement character).

Try resaving the file with LR line endings.

Note: We should probably add a .gitattributes file to ensure that new checkout all use the same line endings.
