Research direction
Start with the linked FreeOrion Process.cpp lines 215-220 and the boost-process-v2-capture branch. Reproduce the hang after adding async_pipe and redirecting stdout and stderr, then inspect why io_context.run() does not return. Done means identifying and fixing the blocking behavior with redirected child output, with a regression test if the repository provides a suitable test location.

Description
I have the code already using boost.process v1 to manage child processes:
If I add boost::process::async_pipe and redirects boost::process::std_out and boost::process::std_err here it freezes on io_context.run().
I've tried to use Boost.Process V2 but it doesn't help https://github.com/o01eg/freeorion/tree/boost-process-v2-capture
