I think the block create:andesite_bricks doesn't exist because it crash my server -> Create issue

Yes, i am aware of that, but that is not what is causing the crash. I am not surprised you can't find the actual cause because structure files are nbt files. Text search doesn't work on those.

I don't think Dungeon Crawl is responsible for this crash. All i can see in the logs is that the crash occurred during generation of a plains village because one of the jigsaw pieces uses the create:andesite_bricks block, which does not exist. Dungeon Crawl does not use jigsaw pieces and is not mentioned anywhere in the crash log.
If you can reproduce the issue, try installing the Cyanide mod and then have it crash again. The additional information it provides might help pinpoint the issue.

I will try the Cyanide mod but I searched on the create mod git and on all addons that I use and I have never found an occurrence of the block "create:andesite_bricks". But I did find some in the Dungeon Crawl mod (for exemple "src/main/resources/data/dungeoncrawl/theming/primary_themes/create/andesite.json").
