Need help with Samsung SM_G965N (star2lteks)

I bought this phone because SGM_G965N was compatible with /e/ Project but I can’t install it. I get a “FAIL!” when I try to install TWRP, do I need a certain “start2lteks” version? What am I missing? BTW I first tried the easy-installer and saw a forum post that it is under beta, to manually install it.

Phone info: Galaxy S9+ (OEM Unlock: ON)

Model Number: SM-G965N
Phone Status: Official
One UI version: 1.0
Android version: 9
Baseband version: G965NKOU2CSI1
Kernel version: 4.9.59-16947869
Build number: PPR1.180610.011.G965NKSU2CSJ1
Android security patch level: October 1, 2019

I can upgrade the firmware, but do I want to? I don’t really want to mess with it since it is currently OEM UNLOCKED.
