Game crashes while generating new chunks

Teleported to a new location in a new world to check out the seed for multiplayer up front. computer gets stuck a few minutes whilst trying to generate new Terrain, midway through, it crashes. I self consider my computer quite decent so this might be a problem to more people. 16BG Ram, i7-8700K 3.70GHz, Nvidea GTX 2070, Minecraft is allowed to use 15G.
