Can no longer drag and drop email attachments from emails to folders after 153esr update

My Thunderbird install updated from 140.13.0esr to 153.0.2esr yesterday and now I can no longer drag and drop any attachment from an email to any folder on my computer. I simply get an error message window with a title of "Error Moving File or Folder" with "Unspecified error" text. See image attachment. I've tried a variety of folders, including Downloads, Documents, Pictures and other folders on local and external storage devices. I can save the attachments using the Save All button, or by right-clicking a file and choosing Save As, but not by dragging and dropping as I have done so for years. I have checked if Thunderbird is running in admin mode, which it is not, but have tested it both ways with the same problem occurring. I have also run Thunderbird in Troubleshoot mode, and the same thing occurs. I tried clearing the startup cache from the troubleshooting page with no change. Restarting the PC did not resolve the issue, and disabling my anti-virus(Avast) also did not make a difference to the issue.
