This bug is due to the fact that raku-json-fast package does not contain the 
precompiled file for JSON::Fast.

This package is a dependency of both raku-json-unmarshal and raku-json-
marshal. So the build process of both package recompile JSON::Fast and both 
ship the precompiled file. Hence the collision.

The issue with JSON::Fast precompilation is tracked there:

All the best
