The first run of a remote play client is usually a setup: find the console, pair it, sign in, map the pad. PPortal skips it where it can, because you have already done all four somewhere else on this machine.
The reader resolves the active profile first and derives every path from it, which is the difference between finding your consoles and finding none: a store read from the default location on a machine with a live profile is an empty list with no error attached.
Version 1.10.0, x64, Windows 10 or 11, built against .NET 10. It installs under an identifier of its own, so an existing chiaki-ng installation stays where it is instead of being upgraded in place, and the two can be run one after the other on the same machine.
