Samsung A53 Stopped Accepting My Password and Locked Me Out of My Phone

I've been using the Samsung A53 for almost three years, and it's been working well so far. Out of nowhere, my phone won't accept the screen password I've been using for ages, and I'm sure it's the right one. I'm really stressed about this situation because I have crucial data on the device, and I can't risk losing it. I've been without a working phone for days, and it's thrown off my routine. I'm really confused about what might have caused this problem and I'm disappointed with how unreliable the device has been. I hope Samsung can come up with a way to keep my data secure and help me get back into my phone.
