LR often goes bonkers without it.

Hi there,

Sorry about the trouble that you see in Lightroom Classic. We're here to help.

Which version of Lightroom Classic have you downloaded? What is your macOS version? Have you tried re-downloading and re-installing the application? Would you mind sharing your workflow? Can you share a screenshot of the error message?

Please try installing and re-installing the Creative Cloud application and freshly install the application.
