yup clean flash. 3t is the device. i wiped every thing apart from internal, but still rebooted back to twrp thrice a row.clean flash ? 3 or 3t? ensure that everything is wiped apart from internal storage. After flash first time it reboots twice due to magisk but havent had any issues with it . There will be new version uploaded later today .
Have you flashed kernel on top of the rom ?
is it rom from.link in op ? If yes there must be something on your side . It does work fine in here flashed several times and no problem . Try re download and flash . Make sure it is clean (Wipe date etc.) and use latest official twrp
