- -close Lightroom app.

- -open LIGHTROOM
- -click LIGHTROOM > PREFERENCES > GENERAL.
- -uncheck "Select the current/previous import collection during import."
- -click PERFORMANCE (at the top).
- -uncheck "Use Graphics Processor."
- -make sure the import folder that it is trying to import from exists. In other words, sometimes the last import location is a external drive that doesn't exist anymore. Change it to somewhere neutral like the DESKTOP.
