Could you please try the following step.

• php bin/magento deploy:mode:show

• php bin/magento deploy:mode:set developer

Clear cache and static and deploy

• sudo rm -R pub/static/*

• sudo rm -rf var/cache/ var/generation/ var/page_cache/ var/view_preprocessed/

• sudo php bin/magento setup:static-content:deploy -f

Let me know your thought after doing these steps.

Thanks, Sam
