Can´t open my project after creating c++ file

I have a blueprint oriented project with Advanced Sessions Plugin. I´ve been working on this project normally, but i discovered that i was missing one thing that i´ve followed on this page:

https://forums.unrealengine.com/community/community-content-tools-and-tutorials/41043-advanced-sessions-plugin

I tried to create a C++ blank file in the editor, as oriented (item 2) but the editor crashes and are not opening again, saying that i might rebuild, when i hit “Yes”, it goes this error: “{Project} could not be compiled. Try rebuilding from source manually”. But i don´t know how to do it, my project is too big to start from the beginning and the c++ file that i created is vanished, can´t even delete it.

Please help, all that i wanted is to create the c++ blank file to run properly the plugin.

I found on internet the solution after long time searching.
Need to delete the folders:

  • Binaries
  • Build
  • Intermediate
  • Saved

Just that.
