Good job on compiling.
Depending on when the “core dumped” error occurs, downgrading ubuntu might not be necessary as long as you use the gcc-7 compiler: Please check here: Segmentation Fault (core dumped) error during mt_prep_snap - #17 by ABraun
Can’t tell if it also solves the problem under WSL, but in many cases this was necessary to get over the first two steps of StaMPS.
