"npm start" fails to create web server (windows 7)

See original GitHub issue

I installed latest version from master (Chrome 98 results, 04/02/2022) (have ran previous versions of benchmark without problem)

I have windows 7 64bit, node v13.6.0 npm 6.13.4.

Have done:

npm ci on root folder

then

npm start to start web server.

But I get following error:

> js-framework-benchmark@1.0.0 start C:\nikos\work\_nikos\open_source\git\js\js-framework-benchmark
> ws -c lws.config.js --static.maxage 1 -d .

I solved the angular issue by using NVS node version switcher on my win7 box and switching to a previous node version supported both by angular and win7 (node v.12.20.*)

I made the following alterations after debugging the issue:

Upgraded node to 13.14.0 (seems 13.6 is buggy)
Downgraded lighthouse module to @9.0.0 (newer versions require features of higher node versions). Now web server works correctly and most benchmarks run, except mem benchmarks.
Added manually Chrome binary path to wedriver-ts/src/puppeteerAccess.ts since puppeteer memory benchmarks are failing to launch chrome binary (now they work).
