Your are right it’s not. However #define HAVE_OPENJPEG is supported and it works for me.
In my local opencv folder (C:\opencv ) jpeg is supported in the cvconfig.h
/* IJG JPEG codec */
#define HAVE_JPEG
so yeah, it’s probably not supported in UE’s inbuilt version which is 4.5.

I hope you found your answer. Your question helped me find a partial answer to my question here.
debugging exceptions in opencv
After reading your post I changed the type to png and everything worked fine !
I still need to learn how I’d go about debugging this via the call stack .
Cheers,
