I was having the same issue, turns out that it was present in web-dev-server - see here: https://github.com/modernweb-dev/web/issues/1483

Short version - Windows paths are not case sensitive but the resolved paths in web-dev-server are, so when the resolver attempts to provide absolute paths to the node modules in order to generate browser paths it is unable to find the referenced imports.

I came across this when running web-dev-server from Powershell after navigating to a project folder using terminal commands that had inconsistent casing. So if my project folder lived here: C:\Dev\Projects\MyProject and I navigated to that folder by typing cd c:\dev\projects\myproject and then attempted to run web-dev-server, I would get that error. Resolve it by simply using the Set-Location cmdlet with a case sensitive path: cd C:\Dev\Projects\MyProject
