Just updated to 7.2 and tried to make a vertical panorama using 5 Sony raw (ARW) files using the cylindrical option and got an "unknown error" result. Tried using perspective option and it worked (preview for cylindrical was more accurate/pleasing). Repeated effort several times, including following a LR restart on a late 2015 iMac 27" i5 with 24gb RAM.
Also, if you use Adobe ID for sign-in, please label it as such, not as a "Photoshop Family ID," which is inaccurate.
