Research direction
Examine the Qt session management warnings in the logs. These suggest that the Flatpak sandbox might be interfering with the clipboard connection. Look at the CopyQ source code, particularly files related to clipboard monitoring and copying (e.g., src/clipboardmonitor.cpp). Check if there are existing Flatpak configurations or overrides that could resolve this. Consult the CopyQ Flatpak documentation and known issues list for similar problems.
