`adb devices` crashes Windows command prompt, how do I root my Samsung device?

I've been trying to root my old Samsung Galaxy Tab A7 Lite (SM-T2227) tablet so I can use Titanium Backup to transfer the data to my new Samsung Galaxy S24 phone, but the adb devices command (I'm using Windows 11 to root it) isn't doing anything at all. It just crashes CMD. How do I fix this? And if I can't, are there any alternatives? I'm pretty new to rooting devices, so answer it like I'm 7 and just found out the bootloader exists.
