Unity Crash on Mac os 2021.3.6f1

I am creating a new scene and following the tutorial here :

I am getting Unity crashes in all sorts of places when trying to follow the tutorial and I have no idea why :/ I got a crash when connecting the noise and height modes, i got another crash when hitting generated on a mapgraph, i even got a crash when adding a new graph to the scene.

Is there something wrong with MapMagic 2 and this Unity version maybe ?
