Cannot type @£$ symbols in Windows 8.1

Question

This is Exception: enter code herejava.lang.NullPointerException: Cannot invoke "com.company.MedicalManagement.repository.DoctorRepository.findById(Object)" because "this.doctorRepository" is null

And this class:

    package com.company.MedicalManagement.dtoConverter;
    
    import com.company.MedicalManagement.dto.DoctorDTO;
    import com.company.MedicalManagement.dto.PatientDTO;
    import com.company.MedicalManagement.dto.RequestPatient;
    import com.company.MedicalManagement.exception.ResourceNotFoundException;
    import com.company.MedicalManagement.model.Patient;
    import com.company.MedicalManagement.service.DoctorService;
    import com.company.MedicalManagement.service.PatientService;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Component;
    
    import java.util.Optional;
    import java.util.function.Function;
    
    @Component
    public class RequestPatientConverter implements Function<RequestPatient, Patient> {

        private DoctorService doctorService;

//Error doctorService is null, this point`

        @Autowired
        public RequestPatientConverter(DoctorService doctorService) {
            this.doctorService = doctorService;
        }
    
        public RequestPatientConverter() {
        }
    
        @Override
        public Patient apply(RequestPatient requestPatient) {
            Patient patient = new Patient();
            patient.setId(requestPatient.getId());
            patient.setPatientBirthdate(requestPatient.getBirthdate());
            patient.setFullName(requestPatient.getFullname());
            Optional<DoctorDTO> optionalDoctorDTO = doctorService.findById(requestPatient.getDoctorId());
            if (optionalDoctorDTO.isPresent()){
                patient.setDoctor(new DtoDoctorConverter().apply(optionalDoctorDTO.get()));
            }
    
            return patient;
        }
    }

Solution

After some intensive trouble-shooting (which even took me to perform a fresh install of my windows 8 operating system) I am finally able to resolve this problem.

The problem is actually one of the utility software that comes with my Gigabyte motherboard. Its called EasyTune available in App Center that controls the overclocking and system performance. Once the program is running or asked to retain its settings after boot, then it disables @£$ keys system-wide.

In my case, I enabled the option "Retain Smart Fan settings after reboot." in order to minimize the CPU-fan RPM as I'm using my computer as HTPC and want it to be quite,

Anyhow, disabling the auto-retain options or uninstalling this utility feature is a confirm solution in my case. I hope Gigabyte would release an update which should fix this annoying problem.

Compared to my other computer, I only have English language (with Swedish keyboard) installed and there's nothing i need to switch between input types in order to type those symbols. Another thing is, i'm able to type-in characters like { [ ] } which can only be entered using Alt Gr key. The only problem is with these characters @ £ $.
