Automator Crashing while moving files to trash...

I have an Automator script that I want to run overnight to delete any files in a particular directory that are older than 30 days. In step-by-step mode in the script, it seems to find the files and then, when moving them to the trash, crashes. There are generally from 1,500 to 2,500 files that are in the directory.

Is there a limit to how many files Automator can work with/move? A test with just a few files seems to work fully on the script.

Late 2012 Mac Mini, High Sierra 10.13.6, 16GB Memory, tons of available disk space...

I can't post the crash file that results. Maybe it makes the post too big? Thanks for any ideas of what to look for or solutions, known bugs etc.
