After migrating with laravelshift from 5.8 to 6.2, receiving Sessions Permission denied error

Question

I've updated my laravel project from version 5.8 to 6.2 using laravelshift. Done running composer update command. getting "file_put_contents(/var/www/app.buyonecollective.com/public_html/storage/framework/sessions/Nu5bUgYOijmGdD6f2GyHjNci7xMcO7rsE0D4jSk3): failed to open stream: Permission denied " Reference SS. Tried running:

1. php artisan config:clear
2. php artisan cache:clear
3. php artisan config:cache

But couldn't get any luck. Any help would be appreciated. Thanks in advance.
