Bug found when trying to print object with jpg image embedded

Hello Alex

Description

Here is a bug I have found, I do not know if it is in the firmware itself, or a problem with the python script. It is an intermittent bug, that does not happen all the time, and I do not yet know exactly when or why, but it happens 50% of the time.

I use Prusa Slicer 2.3.0, Windows 10. Using an Aquila X2, printing from SD card not connected to anything.
I click Print, then I scroll thru the list and find the object I want to print. It does display the small image of the item and it is correct. I click the object, the screen thinks for a few seconds, then I see a blue progress bar, and when the progress bar finishes, it goes back to the home menu. It never starts to print and it does not heat or do anything else.

Sometimes, I just reslice the object and then it works. Othertimes, I can not get it to work, so I end up saving to the card without the image, just so I can print it.

When I slice, with the image python script, it slices fine. Then when I export, I see a black window appear for a second, to run the python script and then the black window goes away, so I cant tell if there are any errors in the python script. I tried to look for logs but could not find any.

I would be glad to try and debug with you.

Thanks for all your efforts and this amazing contribution.

Same with cura (about rebooting instead of displaying image while trying to print)
