EDIT: I've managed to fix this issue. For some reason the game only crashes if I try to load LSPDFR on launch. If I get into the game, then load lspdfr and go on duty the mod works fine. I have no idea why this works but hey, results. Thanks for your quick response Opus. I'm going to leave this here so if anyone has a similar issue they can try this out.
Installed English United states as preferred language, made sure it was setup for speech recognition and made it my language for grammar police. Started game and crashed when forcing duty. Game crashed on the same line as previously.

Anything else I can do? New log attached - although I believe its almost identical to previous. RagePluginHook.log
Very much appreciate the help even if there isn't anything that can be done.
