PPSA17221 · Linux · Process loader fails before game startup: libcohtml.Prospero.prx missing/invalid host ELF

Current conclusion

Minecraft PPSA17221 does not reach gameplay in a Fedora 44 Linux v0.1.3 user report: launching the converted app.elf fails while loading libcohtml.Prospero.prx. Moving the supplied guest module into the host libs directory produces invalid ELF header or invalid ELF OS ABI errors. The process stops during module loading.

A separate Windows community thread reaches a rendered world under different build conditions.

Linux · Process loader fails before game startup: libcohtml.Prospero.prx missing/invalid host ELF

Issues

At ./app.elf start the host loader reports cannot open shared object file libcohtml.Prospero.prx. Copying the bundled source PRX to libs changes this to invalid ELF header; unwrapping and copying it gives ELF file OS ABI invalid. Loading stops before graphics initialization.
