Preview unavailable for this file

[Heirloom Bob]

Upgraded to Lightroom Classic last week and now when I attempt to import from a card, I get the "Preview unavailable for this file" on all my shots. Attempted to import anyways and then get a message that "The files are not recognized by the raw format support in Lightroom". These raw images are in arw format from my Sony and I had no issues prior to the upgrade.

On a side note, the upgrade on another PC works exactly as before. Any thoughts or suggestions?

Uninstalled and reinstalled and the issue disappeared.
