I started to see this consistent interruption of the precompilation stage whenever I install packages in fresh environments. For example, if I start a fresh environment and `] add GeoStats` on Julia v1.10.4, I get the following output:

 ![image](https://global.discourse-cdn.com/julialang/original/3X/3/b/3bc7233aea628e8f2b699d71b1e7b37eab015f4c.png)

The prompt becomes available again, but not all packages are precompiled. When I try to use the package for the first time, the precompilation is restarted.

Anyone experiencing similar issues? Can you reproduce the issue with the package above?

Cannot reproduce on Linux:

```julia-repl
julia> import Pkg; Pkg.activate(;temp=true)
julia> Pkg.add("GeoStats")

Precompiling project...

  1 dependency had output during precompilation:

Thank you for trying to reproduce the issue. I tried on a Windows machine.
