Why does import start automatic in my Lightroom Classic. I have not enablet auto import

In Preferences > General, make sure that Show import dialog when a memory card is detected is unchecked.

Also make sure that Windows Autoplay is turned off.

Hi, thanks for reaching out! Please go to the File menu in Lightroom Classic, then Auto Import, and then Auto Import settings. Verify if you have "Enable Auto Import" checked and a Watched folder set up. 

If you do, uncheck the option to Enable Auto Import and click on Ok.
