EDIT: So i messed up and apparently uploaded the 32bit TWRP by mistake and haven't built a bootable 64bit twrp in a while. I've been debugging building a 64bit TWRP based on an Oreo kernel.

I have uploaded RedWolf recovery which supports both 32bit and 64bit I'm sure of it this time. Sorry for the inconvenience and being a real d!^k to anyone who brought up having error 255 when flashing 64 bit builds in TWRP. This redwolf recovery will resolve such issues.
