Could you please let me know the file type and format of the files that you are trying to import in Lightroom?
Also from where are you trying to import the images in Lightroom, external or internal drive?
I tried to import images (photos and videos) form my iPhone.
I also copied those same image files to my PC-desktop and tried to import from the desktop. File types include: .jpg, .png, .mov
I also get the same error message and crash when I try to play a video in Lightroom. I tired to play an mp4 file and the same thing happened.
I did now have success with importing from an SD card containing only .jpg files. So it does seem as if the problem may be movie files.
Try to convert the Mp4 file to M4A format and then import the files in Lightroom and check if it still crashes or not.
