ArcHydro Create Sink Structures takes forever

I'm trying to run the Create Sink Structures from ArcHydro tools in ArcMap 10.6.1 (upgrade is not an option). Whatever the size of the raster (I tried 3 Go, then cropped it to 37 Mo and now 1 Mo), the script just keeps running and then ArcMap falls into "not responding" mode. I tried working with .tif and gdb raster. I'm using a Nad83 CSRS MTM  projection for all the inputs. I have 8 Go ram, i5 core and SSD disk with 70 Go space left. 

I don't understand what's happening. Has anyone experienced similar issue and found a work around?
