Angular-cli: Angular CLI 9.0.0-next.9 throws error : Unable to copy assets: EPERM: operation not permitted

[naveedahmed1]

🐞 Bug report

After upgrading to Angular CLI 9.0.0-next.9 ng build throws below error

Unable to copy assets: EPERM: operation not permitted, copyfile 'D:\MyProject\ClientApp\src\assets\fonts' -> 'D:\MyProject\ClientApp\src\assets\fonts

Downgrading back to Angular CLI 9.0.0-next.8 fixes the issue, so it seems that the issue is with the Angular CLI 9.0.0-next.9

Command (mark with an x)

- [x ] build

Is this a regression?

Yes, the previous version in which this bug was not present was: Angular CLI 9.0.0-next.8

🔥 Exception or Error

Unable to copy assets: EPERM: operation not permitted, copyfile 'D:\MyProject\ClientApp\src\assets\fonts' -> 'D:\MyProject\ClientApp\src\assets\fonts'
