Damn, sorry to hear that, however by your words I assume the game itself has launched properly, only the configuration was messed up, am I right? If so, that makes me sure there's a conflict into at least one of your xmls. Unfortunately we cannot rely on RPH log at this case, it is not going to display the exact location. https://www.lcpdfr.com/downloads/gta5mods/misc/28735-eup-backup-configurations-93/ - I've used this one as soon as 8.3 version of EUP has been released. I'm pretty sure of its reliability, although I usually adjust the uniforms to suit my own preferences. Try this out and then hit me up. I believe you use Ultimate Backup plugin, it is compatible with this one, so you can make sure whether it works correctly.
