and the screenshot contains (using macOS's Live Text for transcript):

extractbb has changed in TeX Live 2024: before that, it was an alias for the xdvipdfmx executable; since TL 2024, it is an alias for the Lua script extractbb.lua, which acts as a wrapper calling ebb, itself an alias for xdvipdfmx. The script can be inspected at

https://tug.org/svn/texlive/trunk/Master/texmf-dist/scripts/texlive/extractbb.lua?view=markup

I imagine the way that the argument of the script is passed on to xdvipdfmx (in lines 225-234?) may be the cause of what you're observing. Unfortunately I don't really know Lua, thus I can't help.

The problem must be specific to Windows, as I'm seeing nothing of the sort on the Mac:

% extractbb -O "Desktop/Test with space/ImageCropBug-extractbb_2022vs2024.png"

Just one suggestion: include console output as text rather than screenshot, this is more likely to attract people's attention.

Other than that, the script authors' hang out on this list (see last July's archive), so I think this is the right place to report problems.
