I am trying to traverse through SharePoint Online Site collection using Powershell CSOM. I am able to go to the last folder from the root folder which is 2-3 levels down. But I could not search through all the document libraries as it gets struck to one
of the last document library.

Below script is working for me. I can now traverse through all the folders and subfolders including the root folders to fetch all the files using Powershell and CSOM.
#function begins
                    function Recurse($RootFolder) {
                        $Context.Load($RootFolder)
                        $Context.Load($RootFolder.Folders)
                        $Context.ExecuteQuery()
                        $Context.Load($RootFolder.Files)
                        $Context.ExecuteQuery()
                        $resultCollection = @()
                        foreach($file in $RootFolder.Files)
                            $resultCollection += $file
                        foreach($folder in $RootFolder.Folders)
                            if($Folder.Name -ne "Forms")
                               Recurse $folder  
                            Return $resultCollection
                    # Function ends
