Updated Photoshop to 25.11 this morning on a MacBook Pro running Sonoma 14.5 and no longer able to open PDF files in Photoshop. Tried a variety of files created previously be me and others from outside my organisation.
All flag up "Photoshop could not complete your request because of a program error"
Rolling back to Photoshop 25.9.1 does allow PDFs to be opened so looks like a 25.11 bug.
