Running the streaming client directly returns issue regarding SDL3 not being installed (SDL3 is not even ported to Fedora) but I assume it's supposed to be ran inside the Steam runtime.

So either for some reason streaming_client is not running inside the Steam runtime or something's wrong here.

Attempted to reproduce on a Flatpak build, and Remote Play works perfectly fine inside a Flatpak.

Also having this issue on Manjaro, definitely related to the May 7 update. Some other interesting caveats:

• I don't know if it's always been like this, but there's an ubuntu12_64 directory and an 'ubuntu12_32' directory, each with their own streaming_client. The 12_32 version works from the command line (or at least, gets as far as opening a window and saying Couldn't find a streaming game for your account on the local network). The 12_64 version instead throws ./streaming_client: error while loading shared libraries: libSDL3.so.0: cannot open shared object file: No such file or directory on launch.
• However, a libSDL3.so.0 exists in the ubuntu12_64 directory, and that version of streaming_client gets to the same window as the 12_32 version if I prepend it with LD_LIBRARY_PATH=. in the ubuntu12_64 directory.

For further clarity, this is the exact error message I get from steam when trying to launch a stream:
