ENOENT: no such file or directory

I have the above error message and have looked at all the relevant posts that seem to date back forever. So a recurring error for users?

I have reinstalled everything - Ionic 6.11.11, npm 6.14.8

I see in the url to the app that it includes \OneDrive\ despite the fact that I don’t have that on my system. I can’t purge the url to remove it. I have cleared the caches etc. That of course, if it’s the problem which I am not sure of.

Any ideas please? Thanks, Bruce
