Program won't export stop motion project

Hello there.
I’m making a stop motion short for college, but Shotcut won’t export.
I’ve tried to export multiple times, but it’s stuck at 0%.
I’ve also tried to export it in 720 instead of 1080.
Other projects I’ve done have exported easily without any errors. Maybe this project doesn’t export cause it’s a series of images instead of video?

Processor: Intel Core i3-7020U CPU @ 2.30GHz
Ram: 4 GB
OS: Windows 10 64 Bits

How many images?

I’d say around 4k. We took a lot of pictures but I didn’t use them all so I’m not really sure.

Also, I forgot to mention there’s a few videos too.

Shotcut does something like an inventory of all media before it starts exporting. With that many files, it could sit on 0% for awhile before looking like it really gets going. It may take patience. If it still doesn’t export, cancel it and send us the job log.
