After I introduced cscore, I threw the following exception

Seems like the LatestCsCoreVersionChecker.cs in line 25 cant access the URL https://raw.githubusercontent.com/cs-util-com/cscore/master/CsCore/PlainNetClassLib/src/Plugins/package.json , are you able to open that URL in your browser? Maybe it's blocked in your network. Which Unity version are you on?
