that is strange!
I could imagine:
- IMG_20260615_195853218.jpg is in a directory with a symlink
- the command uses a relative path that ImageMagick interprets badly
- the full path contains something that matches a blocked pattern

To test this copy the file in a non-suspicious directory 
(/home/carlos/), cd to there and write the command (not run the script)

If it works it was one of the above reasons.

If not,
- paste the exact command you are running
- paste the output of
magick identify -list policy | grep -E 'path|coder|module'
- tell me the exact ImageMagick version (magick -version)

I'll test here and see if I find out something (no guarantee...).
