Good rule of thumb, do not
install OTA updates on any modded Android device, without at a minimum doing thorough research on what will happen.
Depending on the device and the update in question, attempt to install an OTA on a modded device will remove root, possibly plug existing exploits (and render the phone unable to be rooted), or put you in a boot loop (as you have experienced).
In particular, OTAs require stock
recovery in order to install. So if you have custom recovery installed, this is why the OTA install is failing (and why it keeps booting into TWRP).
Also, there is little (if anything) contained in the OTAs that doesn't get posted in a safe format (flashed from custom recovery) in the Development section soon after the OTAs start to roll out.
