Purge cache = Error : JFolder::delete

[BigStef]

Hi,
I have just upgraded my Joomla from 3.7.5 to 3.8.0 and get now a message when try to purge cache ( with core purge or Regular lab Cache Cleaner) :

JFolder: :folder: Path is not a folder. Path: /home/crnc/public_html/cache/Joomla/CMS/Helper/LibraryHelper::loadLibraryjoomla_lock

Actually i have now two folder I have never seen before in my cache folder :
1st folder : Joomla\CMS\Component\ComponentHelper::load_lockComponentHelper::load_lock
2nd folder : Joomla\CMS\Helper\LibraryHelper::loadLibraryjoomla_lock

Note that this is not path of folder but the name of it!
I can't erase them with purge tools, i can't erase them through FTP
And I can't purge my cache anymore as as long that folders are there, purge won't work.

The only things I found about that issue is on the github : https://github.com/joomla/joomla-cms/pull/17381
But it doesn't talk to me.
If anyone would have an advice, it would be great, thanks in advance.

OK, I have found a solution to avoid this issue :
1/ Go to Global configuration
2/ Set Cache Handler to "File" - or verify it is set so (mine was on Cache_lite)
3/ In your cache folder AND in your administrator cache folder, erase your files/folders with path in their foldername through Cpanel (or ask your host support).
Et voilà...
