With 2022-11-01, LaTeX is beating around the bushes but docstrip.tex is finally asked for and, of course, found. With 2023-06-01, only docstrip (without extension) is searched for and not found. The Prote engine is exactly the same (these two versions of LaTeX are simply a link to the very same executable; only the format is different ---the dump of the macros). So obviously, something changed and that is not recorded in the ChangeLog. So I'd like a LaTeX developer to make a diff between the files that have something to do with \input (your code base is too huge; I don't know the intricacies of l3 and the rest, so I need someone to trim this to narrow the part I may be interested in) in order for me or a LaTeX developer to spot what has changed.
