Same issue here on both my MacStudio M1 Max and MBP M1 Max running Sonoma 14.2.

I am having problems with Spotlight dependent applications including HoudahSpot and Hazel. Hazel is reporting errors related to not finding metadata for files, causing automated filing of files not to work. HoudahSpot searches fail. Rebooting corrects the problem briefly (hours) but then spotlight failures return.
