The hosted runner lost communication with the server. Anything in your workflow that terminates the runner process, starves it for CPU/Memory, or blocks its network access can cause this error.

Should we be warning about it from rustc and/or erroring out?

Honestly? I don't know.

I haven't tried that but it should be possible to make split debuginfo work with the right combination of linker flags. For example when linking with LLD one can add argument to create .pdb files with debuginfo. I don't know whether this needs compiler support.

I'm totally clueless whether split debuginfo is possible with Dwarf on Windows.

Because rustc doesn't handle split debuginfo for these targets, enabling that option causes them to be missing some of the debuginfo.
