Python error when running Cost calculator on QGIS 3.14

[yukon-aik]

Good day. I have the GeoTrace installed successfully on W10, QGIS 3.14, python v3.7.

I have tried running the cost calculator using my own geological image and also tried the Bingie Bingie Survey QGIS project.
However when running the cost calculator, only "darkness" able to output a new raster while others throw the similar python error like below:

2021-03-26T14:41:24 WARNING Traceback (most recent call last):

self.arrays.append(np.rot90(array,3))
AttributeError: 'CostCalculator' object has no attribute 'arrays'

Please can you provide help on this?
