Same problem for me, tried installing fresh (wiped OS, data, cache) with latest TWRP, entered boot loop, got taken back to my old ROM.
When you flash OS it's going to be installed to the inactive slot so you need to boot into other slot.
Also the lastest ROM is encrypted so TWRP will not stick unless you format data, not just wipe it. The new ROM is going to overwrite it so reboot and format data, Use JLB script before installing Magisk and if you want TWRP flash the dm-verity.
