darktable 2.6.2 for Windows 10 is now creating blank files upon export

Software darktable
1

To Whom It May Concern:

During the last two days, when exporting darktable edited files to jpeg, png, or tiff, the files are blank; nothing is in them. I have reinstalled darktable 2.6.2, but it does not help. Before that, darktable worked fine.

I have been editing raw NEF files from my Nikon D3400.

Can someone please help me.

Sincerely,

Tom Lewis

Can you post a problematic raw and xmp file?

You can also start darktable from the command line, do the export, then paste the command line output here. Use C:\path\to\darktable.exe -d all.
