Assets not copying js and css


I was doing changes in assetmanager configs linkassets and forcecopy and I don’t know wat changes I did, few of the js is not loading in assets folder and few are loading. Although the Path assets/xyz/abc. Js is showing on the page but it says the source not found. Currently linkassets is true and forcecopy is commented. And few js is not getting copied as a result few extensions are not working.
