I have solved the problem by deletion the generated folder (I restored it from the Magento distributive).

It looks like the same issue: Magento 2.3 bug on Windows: «Command line user does not have read and write permissions on generated directory»

Hi ,
I have solved the problem by running the command setup:di:compile .

According to Magento, this serves the following purpose:

  • Application code generation (factories, proxies, and so on)
  • Area configuration aggregation (that is, optimized dependency injection configurations per area)
  • Interceptor generation (that is, optimized code generation of interceptors)
  • Interception cache generation
  • Repositories code generation (that is, generated code for APIs)
  • Service data attributes generation (that is, generated extension classes for data objects)
