Reviewed multiple repair sites which pointed to heating elements being a consistent reason for this problem - even in newer model dryers like mine. Following another repair site video, began taking apart dryer, but it didn't show all the required screws on my dryer. Found Fix-it-Felix on youtube which lead me through remaining process to remove the heating element. I recommend taking photos of the element casing when you first pull it out - top to see where screws go, side to see where wires go, and another picture when you open the casing.
Quick inspection with flashlight found the break in coils. Lots of different options to purchase replacement heating elements from $15 knock-off to OEM at about $150. I chose OEM after seeing several poor reviews on the knock-offs. Since my dryer is under 3 years old, I plan to keep it for several years. If you were planning on buying a new dryer in a couple months, might be worth taking a chance on a cheaper heating element. Appliance Part Pros was middle-range priced for OEM ($135), but very helpful in details and research on the item, it's replacement process and had great reviews on timely delivery.
Element arrived in 3 days which was awesome in Covid time! Appliance Parts Pros repair video was watched to instruct how to replace element and reseal the dryer. Very helpful and similar to my model. As others have written, there was a strong metal burning smell on the first running of the dryer, but it went away by the 2nd load. We have done 5-10 loads and all is well so far.
