I would also add that it only seems to be that specific file since using other AdvancedHook.dll's such as the one that come with ELS won't cause any incompatiblity issues.
However, I found that deleting this file from the GTA V directory solved the incompatibily issue with the only negative side effect being that you will no longer be able to use/enter the locker room in the downtown police station (all the other police staions still work regardless). Anyway based on my testing it seems that GTA Redux is incompatible with the AdvancedHook.dll that comes with LSPDFR (I always use the manual install of LSPDFR). It would stand to reason just depending on the amount of mods you have installed, I personally install a exessive amount of mods and spend more time fixing issues and doing reinstalls than actually playing the game since I came to realize that I simply refuse to play without GTA V Redux in addition to my must have mods such as LSPDFR, ped models, weapons etc. I did some extensive testing since I was still determined to get this to work since I hypothesized a conflict might be the issue as stated.
