Guud

Hey guys, i need some help, every map i create after getting to some point, like after spud guns and a truck with 7 or 8 collectors, the game crashes 5 min after starting, like first it crashes softly and suddenly the game just stops working, and it happens every single time and i dont want to create a new map when i already have most of the things i need on this one. Do you guys know how to fix it? My computer can run it smoothly, here are the main specs:
Intel i5 10400F 6-Core w/ Turbo 4.3GHz
Zotac GTX 1660 Super Twin Fan 6GB GDDR6
16GB (2x8GB) Team Group Elite 2400MHz
