Uninstall twrp without wiping data

[dzmike2100]

Hi, please, I need help. I wanted to root my note 8 (exynos) using TWRP (with odin) and MAGISK. But at the reboot in recovery mode, TWRP asks me to wipe my data, something I don’t wanna do of course. The problem is i can’t go back because the system reboots in a loop and I can’t make a backup of my rom with all my data because it doesn’t recognize them, when I mount a partition I can’t select data. Thank you for helping me because I don’t wanna lose my files.
