The canal is shallow at the sides, for a ship as this, this creates a suction when it's not in the middle.
The captain wasn't going straight ( zigzag) and while he wanted to get out of the suction on the left side, the ship turned way too much to the right.
There's a really good animation here at 1:03 in the video ( dutch): https://www.vrt.be/vrtnws/nl/2021/03/29/zeevaartschool-maakt...
Video is talking about a "sea driving school" that simulated the incident in their simulator.
My info above is the Dutch information required to see the video from 1:03 till after the animation.
