Same problem; worked before modpack, works in safe mode. Files are attached for investigation.
I haven't been using that mod and I'm still having the issue. Must be something else for me.
I have the Female Crewmembers selected and installed but the default crew pictures will not change in game. Thank you for your modpack and your assistance. :)

Worked for me. Make sure you deselect "Remove the contents of DLC cache (Aslains_DLC_cache folder) at the Installation Type screen; and thank you to the OP for this walkthrough.
