An internal error has occurred?

Trialing DxO PureRaw 2 on an Mac studio M1 max. When processing .RAF files with DxO Lightroom classic plug-in, I get an error " An internal error has occurred" … the file processing bar completes pretty rapidly, but then nothing happens for quite sometime before I see an associated DxO folder created to hold the new DxO created file, but sometimes it doesn’t show until I hit the LR sync folder button, this is when I get the error dialog box. Note the image then does appear in the associated DxO folder. I am saving my images on a Crucial X8 and Seagate external SSD’s.
