Trouble importing PDFs from Canva since 7 February 2024

PDFs created in Canva imported into CorelDraw perfectly until 7 Feb 2024. All PDFs created since then say the file is corrupt when trying to pull it in to Corel. The PDFs work fine in all other software I have tried and PDFs created before the specified date work just fine in Corel. Has anyone had the same or similar issue and if so, have you found a solution?
