I recieve an error "First chance exception at $76C008B2. Exception class EClassNotFound with message 'Class TPanel not found'. Process KNP.exe (38460)" during debugging and application throw exception. I am not use if I deleted something that causes this error. Already spend days on this and stuck.

When I run it without debugging application error message window pops up "Class TPanel not found" right after application exception. Also stucks at below underlined line.

public:
/* TCustomForm.Create / inline __fastcall virtual TForm(System::Classes::TComponent AOwner) : TCustomForm(AOwner) { }
/* TCustomForm.CreateNew / inline __fastcall virtual TForm(System::Classes::TComponent AOwner, int Dummy) : TCustomForm(AOwner, Dummy) { }
/* TCustomForm.Destroy */ inline __fastcall virtual ~TForm(void) { }

public:
_/ TWinControl.CreateParented / inline _fastcall TForm(HWND ParentWindow) : TCustomForm(ParentWindow) { }

};
