I am having somewhat the same symptoms as you have.

It looks like the problem occurs at the bootstrap of the classes. The weird part for me is these are core classes and thus part of the main product. It is strange that at a point where the installation is fresh that the error is happening.

Any help/assistance will be greatly appreciated.

Hi, sorry for the late update.
but after a big headach I decided to
Reinstall the mws Instance
Recreate the mws DB component(cause of some configs in binary fields)
and it works now
sorry no better Idea for now
