Failed to export a photo: Internal Error (Correction failed on Execute stage)

This happens to me for the first time, but after some editing on a TIFF I got from a panorama shot, this photo can no longer be exported from DxO PL7. It throws an error as the export progress bar is almost done, suggesting:

Internal Error (Correction failed on Execute stage)

I have tried to reopen the software but the same error shows up when I export. Where should I start to debug this?

(Also just submitted a support request to DxO)

I have attached the concerning photo (I leave the JPG version here) and the .dop file.
