When I trie to render blender shuts down. Tested on version 3.4 and 2.93. Maybe it's the RAM fault, but I'm not sure.
I also tried rendering on the cpu (i5-10600).
OK eh....., I reduced the level viewport to 2... and it worked.
I think that the problem could indeed be too little RAM (up to 100% utilization).
The map finally rendered in 30 seconds and looks fine.
