Please remove node_modules folder and install it again.
We had the same problem at the customer site. Turns out, they opened access to npm repositories; but in order to download Chromium, puppeteer tries to download from https://XXX.1e100.net which was blocked (it's Google download site, but it shows up on suspicious lists; so it was blocked). Third-level domain varies, but it is something like mia07s48-in-f16. Anyway, once they opened 126.96.36.199/24 subnet, it started working.
Hope that helps somebody
