Malware Warning About a File I Created

Dear community,


under macOS 15.6.1 (24G90) on a Mac Studio, the Mac refuses to open files (eg. a pdf written by my—legally used and up to date—InDesign) and warns about alleged malware. The same Mac opened that same file yesterday without hesitation, and the file hasn’t been altered since.


Would anyone know what is going on here?


Thanks!

Mac Studio, macOS 15.6
