You can only leave your residency before 45 days are up for an extreme hardship -- like a spouse/close family death, personal reasons such as just being diagnosed with cancer and need to delay, no longer are match eligible (ie, you failed final exams), or you decide that you no longer want to practice medicine. Other than that, you're stuck for 45 days. If you reach out to another program before those 45 days are up, you have violated the match and you can have your contract voided and be barred from participating in a match institution's GME for 3 years. It is NOT WORTH IT
