Boost.Asio 1.78 fails with stream_file

[germandiagogomez]

Using Ubuntu 20.04 
g++ (Ubuntu 11.1.0-1ubuntu1~20.04) 11.1.0
quickemu ppa added for liburing: https://github.com/quickemu-project/quickemu

When using Boost.Asio 1.78, to use the new stream_file API I had to define BOOST_ASIO_HAS_FILE by hand (not sure this is intended).

When using the new stream_file, without defining BOOST_ASIO_HAS_IO_URING I get the following compilation error, which disappears when I define BOOST_ASIO_HAS_IO_URING. However, when defining BOOST_ASIO_HAS_IO_URING the run-time gives an invalid argument error:

I tried with standalone Asio as well. Same problem as in my original post at the toop-level without ASIO_HAS_IO_URING. With ASIO_HAS_IO_URING I get another compilation error, though (it does not even compile, unlike with Boost version, which compiles but I seem to have run-time problems):
