I would search for all the files named catalog_product_view.xml in your project and check if one of those files are in one of your module list. Then try to disable those modules one by one like Shoaib Munir said.
First, you need to list down all the enabled and disabled module by this command:
php bin/magento module:status
After that you need to disable your newly added modules one by one by this (Instead of Vendor_Module use your module name):
php bin/magento module:disable Vendor_Module
Run following commands after disabling modules
php -dmemory_limit=1G bin/magento setup:upgrade
php -dmemory_limit=1G bin/magento setup:di:compile
php -dmemory_limit=1G bin/magento setup:static-content:deploy -f
php bin/magento cache:clean
Once you find out the module that is effecting product page layout then enable all the disabled modules which are not effecting page layout and you have disabled it for testing
php bin/magento module:enable Vendor_Module
Then run upgrade di:compile and deployment command again.
