Hi, everyone.
I’m trying the upgrade my probuilder. My current version is : 5.0.3
I’m getting this error code:

An error occurred while resolving packages:
  One or more packages could not be added to the local file system:
    com.unity.probuilder: EBUSY: resource busy or locked, open
'C:\Projects\..\Library\PackageCache\.tmp14980Hq9TwV2S61oa\copy\Editor\EditorCore\HierarchyListener.cs'

I deleted PackageCache and reopened but i didn’t work.

How can i upgrade my version?
