P.S. Have tried disabling all plug-ins. Makes no difference.

Try rebooting your system after making sure all plugins are disabled. Try the slideshow again.

Make sure none of the selected files is missing and has a '!' icon on the thumbnail.

Hi David,

Are you facing this with different catalogs as well?

Could you share your catalog file to keniya@adobe.com along with the sample set of images where you are facing this issue?

Thanks,
Smit

It would be helpful to collect a traceback log to determine where the error is coming from. Instructions https://forums.adobe.com/thread/925598.

Hi David, did you generate the traceback while you are reproducing the "An internal error has occurred: ?:0: attempto index a nil value" error?

After looking at the log file that David sent me privately, I am able to help David resolve his issue.

Resolution:
Make sure that you have read/write access to this directory on your system

Windows: \Users\your account name\AppData\Local\Adobe/Lightroom\Caches\velo\
MacOS: /Users/your account name/Library/Caches/Adobe/Lightroom/velo

Or you can simply try to delete the folder altogether.
