Xiaomi Poco X3pro Shuts Off By Itself And Cannot Be Turned On

I've had it up to here with my Xiaomi Poco X3 Pro. It's been playing this annoying game of shutting down on its own, flashing the Poco logo like it's going for a record. And when I dare to press the power button, it's like hitting a reset button - back to square one. This glitch started acting up right after the warranty period threw in the towel. So, I gave the authorized service center a ring, and what do they hit me with? Since the warranty just expired a few days ago, they're throwing around this "pay up for repairs" vibe. Seriously, what's the deal with that move? what's your aim? I'm done with you.
