PDF not converting to searchable PDF

Over the last couple of days Devonthink has not been converting PDF’s to searchable PDF’s on either import or manually. It appears to go through the routine, one sees the progress bar, recognising, analysing and collating, creating a new copy but not actually converting the file.

Rather odd, software up to date, restarted program and computer , 2013 iMac , any thoughts…

Thank you for the link, I will wait for an update.
