minecraft world creation error

[Jaxon Hellsing]

Hello! I got an error saying that errors in the currently selected datapacks prevented the world from loading. I tried pressing safe mode but it does nothing either. this is my debug log https://paste.gemwire.uk/view/6b32730d

There is a bunch of errors, but this one seems like the culprit:

[04Mar2022 18:35:23.471] [Render thread/WARN] [net.minecraft.client.Minecraft/]: Failed to load datapacks, can't proceed with server load
com.google.gson.JsonParseException: Error loading registry data: No key arch_block in MapLike[{"arch_blocks":["minecraft:stripped_dark_oak_log"], ...]

The log doesn't tell me who's at fault though, but if I can wager a guess, I'd say "Repurposed Structures". Try downgrading that to repurposed_structures_forge-4.2.6+1.18.1, maybe?
