Unwanted craks and taers on my printing

Hello,

It is the 4th time that cracks and tears happen in my printing.
Please find pictures attached.

I use phenom L with peopoly deft gray resin.

I don’t really understand why the piece looks also crushed in this area.

Could you please help to find why ?

Many thanks,
Virgile
