Anything Else?

Server logs after the crash: https://mclo.gs/y9oGXPc

100 blocks is fine.

yes, because your 100 block selection is not within the chunk that your server is failing to generate. your logs indicate this is a server issue, not a worldedit one

this looks like an issue with your server, not WorldEdit. it's stalled because you tried to edit a block in a chunk that the server is failing to generate. the same would happen if you just walked there, or if anything caused it to load.

in general this kind of error can only happen if the server took >60s to set 100 blocks, which is a ridiculously long time, and means something else is going wrong. in your case, something is causing chunk generation to stall.

this is not 20 million blocks but about 90 trillion. also your server was lagging just trying to teleport you to one corner of your selection. it's clearly not going to be able to handle generating and loading 1.5 billion chunks in one go.
