Autofeaturizer stuck at SineCoulomb Matrix

Hello Matminers!
I’ve tried out Automatminer (1.0.3.20200727) on my data using the ‘express’ setting and on one of the iterations, it got stuck at the SineCoulomb matrix featurizing. Below is the log:

As it just gets stuck, I have no error message that could be helpful. It’s interesting that the code had no problem carrying out the SineCoulomb Matrix featurization on a previous iteration (took around 20mins).

Best,
Peter

PS: I also ran into the same issue as described here: Error: Found array with 0 feature(s)
