[Windows][App][Projects] False “files could not be synced” warning when project sources are available

What issue are you seeing?

When I create a new Chat-mode conversation inside a ChatGPT Project, the app displays a warning stating that every project-source file could not be synced.

However, the supposedly unsynced files subsequently appear in the new chat’s available project context and can be accessed normally. The warning therefore appears to report a failed project-source handoff even though the handoff succeeds.

The warning count follows the exact number of project sources: it reported two unsynced files when the project contained two sources, then three unsynced files immediately after a third source was added.

What steps can reproduce the bug?

Feedback ID: no-active-thread-01a00fc4-754b-7952-b6fe-80f886c8c245

What is the expected behavior?

When a new Chat-mode conversation opens inside a Project, its project sources should be made available without a false synchronization warning.

If any source genuinely fails to sync, the warning should identify only the affected file or files and those files should actually be unavailable to the conversation.

Additional information

This has been reproduced repeatedly.

The warning changed from “2 files could not be synced” to “3 files could not be synced” immediately after a third project source was added. Despite both warnings, the complete set of sources was subsequently supplied to the new chat.

No file corruption or actual loss of source access has been observed. The practical problem is that the warning makes it impossible for the user to know whether a new conversation has received complete project context.

The report names no source file, test, or code entry point; begin with the Windows Project-to-Chat source handoff described in the issue and the supplied feedback ID. Done means reproducing the false warning, identifying why its count differs from actual availability, and confirming that warnings only name sources that are genuinely unavailable.
