My guess:

OpenCV fails to load images whose pixel resolution is more than signed int16_t.

For example, I get a similar assertion failure when running OpenCV's remap on a JPG of size 34142 x 17071.

This is documented on:

https://docs.opencv.org/3.4/da/d54/group__imgproc__transform.html#gab75ef31ce5cdfb5c44b6da5f3b908ea4

Due to current implementation limitations the size of an input and output images should be less than 32767x32767.
