Yes, raw files from Sony (.ARW) display as a pink mess in my photo viewer too, but that's nothing to be concerned about. Download Sony Imaging Edge Desktop software (free) here - https://imagingedge.sony.net/en-us/ie-desktop.html . You can do a lot of stuff in this software like adjusting white balance, contrast, shadows, highlights, the creative look, sharpness, etc. because it's shot in raw. Then go to file > output and convert to .jpg. The help section also tells you how to batch convert.
