this not related to the sculk snapper nor is it fabric. open a new issue

Ok, but I have a question because I don't know exactly how chunks work. If this chunk is first, i.e. where the portal is, what will it be called?

Is there a way to delete him completely?

You'll have to delete the chunk where the Snapper is. This issue has been fixed and a hotfix will be releasing soon.

Will this ever be fixed? bump

still not fixed

still not fixed.

temporary fix until the next update is to use /kill @e[type=deeperdarker:sculk_snapper]

Fixed in 1.2.1
