If it helps with debugging. I also had difficulties with Batch processing in parallel. I was converting CR2 files to JPEG with no other macros or image enhancements; just a straight conversion. The CR2 images were created with the Canon EOS Rebel T5i. Pictures were taken in 2016. The dimensions are 5184 x 3456 (about 24 MB each).
I have your basic HP 450 G5 with 8GB RAM. 4 Cores and 8 processors.
I selected 65 files for the conversion. The originals and output folders were on another machine on the LAN. I mapped drive "S:" to that remote storage location.
When I started the process, PHOTO started converting the first 8 files (guessing it was loading up one photo per processor). The machine became unresponsive with 10 seconds, mouse would not move, task manager froze, etc. The "processing" indicators beside the files froze as well. Task Manager froze as well. After what seemed like a couple of minutes. PHOTO just shutdown with no messages on the screen.
I checked Windows Event viewer and it contained the following error in the Application logs:

As a note I am running windows 10 PRO 21H2 OS build 19044.1348 experience pack 120.2212.3920.0.
As a note, there was no file actions in the output folder.
I tried this a couple of times. The first was my first attempt at using this feature. The second was with task manager on, which did not help because the whole machine was freezing up.
I tried a third time but with only 4 files and task manager on. The process completed in about 4 minutes.
In Task Manager noticed that in the first 2/3 of the time my Local SSD drive was at 100%, and memory usage was at 7.5/7.7, CPU usage was peaking at 50-60% . Then during the last 1/3 local SSD usage went way down, memory usage when to 5.3/7.5 and CPU usage went to 100%. Mouse movement and Task Manager became jittery.
The process completed with the four files being converted to JPG. I tried to repeat the process with the next 4 files. This time the PHOTO terminated after being at 100% CPU utilization for a minute in what seems as the second stage of processing.
I really like this application and what to see it "take over the world". I can provide you with CR2 files if you need them.
