Problem exporting a slideshow in Lr Classic 9.4

[AWhite]

Any ideas on how to export 387 photos from the Slideshow module.  I tried several of the export settings from the lowest to 1080 and high and standard.  Export just sits on exporting option.  I even let it run over night and nothing got created.

I have windows 10 64 bit and 580 GB of free diskspace.  LR was using 4 GB of RAM (my system was using 60% of available ram).

First up, I assume you have followed this:

correct?

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Past that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

and 580 GB of free diskspace.

Is that the hard drive your catalog is on? If so, how much free space in percent (%)

Needs to be at least 20%

What drive, what folder, are you exporting to?

You have some great questions and tips for submitting my problems.  Thank you for all the details!  I was exporting to a folder on my desktop.  Anyway after some windows 10 update, I tried exporting again and everything exported.  I have no idea what happened or why it started to work.  Do you still need the info to help prevent this in the future?  I don't mind posting if it would help.
