VS2026 gives error bar "Razor InlayHint Feature" is currently unavailable due to an internal error

.. looks like it's a consequence of the issue i just filed #12487

Anyway, Here's the stacktrace:

this one is reappearing whenever i switch tabs in the editor, gonna restart VS, just for additional context.

Did restarting fix this? I think we'd need a dump or trace to investigate, it seems like it could be caused by the same issue as the other bug, where the editor is sending us bad data.
