Magento 2 Class Magento \ Store \ Api \ Data \ WebsiteExtensionInterface does not exist in [Magento

[andrea_valentina]

Switch to developer mode through the console and now I see these exceptions

Try the commands from the console

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

and 

php bin/setup:di:compile

but both show me these errors, delete the generator folders, and the var folders but even so I still see these errors.

I got this link but it still does not work, Magento version 2.2.3, I need help, I do not know what else to do.

It should work with remove generation folder, var/di var/cache

then run setup: upgrade, setup:di:compile, setup:static-content:deploy

It will work.
