Doctrine models of Attributes causing cache issue.

Hello, Thank you in advance.

I just set up the new Shopware in my local system, I have also posted the question like below, but this is the fully described issue.

When I am trying to clear the cache or even executing the frontend URL, it gives an  Parse error : syntax error, unexpected ‚;‘, expecting identifier (T_STRING) or variable (T_VARIABLE) or ‚{‘ or ‚$‘ in  /opt/lampp/htdocs/shopware_demo/var/cache/production_201909250854/doctrine/attributes/Site.php  on line  167, where  var/cache/production_201909250854/doctrine/attributes folder contains cached doctrine attributes model, while i checked the same folder in my another setup, there is no issue.
