I also faced such issue while working on a laravel project and after several rearch I found a solution which worked for me and it was really unexpected for me and that is the below command you can use in such scenario.
Additionally, you can also use these below command collectively to avoid any other cache issue of laravel.
php artisan cache:clear
php artisan config:cache
php artisan view:clear
php artisan route:clear
Hope it will solve your problem.
