Problem with extensions caching: Serialization of 'Symfony\Component\Finder\SplFileInfo' is not allowed

[arnisjuraga]

/public_html/system/library/Extension/ExtensionManager.php:60

            /** @var SplFileInfo $extensionPath */
            foreach ($finder as $extensionPath) {
                self::$extensionCollection->add($extensionPath);
            }
 
ERROR  -->>         $cache->set('extensionCollection', self::$extensionCollection);
 
        }
    }

try change line $extension->path = $extensionPath; to $extension->path = $extensionPath->getRealPath();

I've tried, but that seems to not help.
