When trying to segment by (1) painting selected slices and using ”fill in between slices” or (2) “grow from seeds” the program crashes and exits a few seconds after pressing “initialize”. The number of slices involved is not very high (about 100). Could the problem be insuffient hardware? My graphics card is Nvidea GeForce RTX 2060, CPU is Core i5-9400F, 2.90 GHz, 16 GB RAM installed.
