Thanks so much, that solved the problem!
Again, If I click on List Participants on the back end, the links in the View Details column work

It really seems this is happening only when I use the pdf_list shortcode ( [pdb_list template= bootstrap search=true sort=true] ).
I already tried to turn off the theme and Elementor to see if they are for any reason interfering but the problem still persists
Thanks for your reply!
Yes, I have a text already on that field, see below
