After I have installed Catalina, I am not able to export more than ca. 5 photos before Lightroom freezes. Then I have to restart my computer, as Lightroom wouldn't open again. I am not able to deliver photos in a timely manner which is a high business risk and not even the disabling of the GPU helped any further. Using the Adobe Creative Cloud subscription for photographers incl. a MacBook Pro 2017. All updates are done. Please help!
