Who I have the same questioned this topic

My phone is a s9+. My phone was opening up in safe mode nonstop today. I tried turning it off via drop-down widget, it reset the phone, but still opened back up in safe mode. I then tried simply restarting the device and it kept opening back up in safe mode. I then restarted the phone and opened up the maintenance boot mode. This is where I am currently at. I've been stuck on this screen for a while now. I can scroll with volume up or down. I cant select anything with the bixby button. and holding the power button only makes the phone go back and then reopen back up to the maintenance  boot mode. It won't turn off or anything. I'm simply stuck.
