This is actually a well-known change in numtide/devshell inputs, which dropped flake-utils.

You may watch out for this pattern follows = "flake-utils"; or follows = "std/flake-utils"; or similar and drop it.

Standard itself does not bundle-load devshell anymore.

Do you have more context on where devshell is defined?
