I too have the same issue.
I have tried:
Fix
Open the RAGEPluginHook settings menu (hold down SHIFT immediately after clicking RPH)
Increase 'Plugin timeout threshold' to a higher value (e.g. 30000)
Save and Launch
I have set RPH:
Windowed mode, window mode no border, Timeout 10000,20000,30000,35000,40000,50000 and 60000 and combinations of all of these.
I deleted the game and ALL user file saves and directories, reinstalled. (Twice)
Windows 10 IS up to date
AVG disabled or enabled, changes nothing
I CAN run GTA V
I tried running RPH with no mods or with, still no run.
I tried running GTA V, open story mode, load RPH, still no run
I've read Redit support on this, watched youtube (including the french one)
Trainer works: TrainerV
I created Mods and Scripts folders (Empty)
I am at my wits end. I love this mod and had few issues with v3. PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!
P.S. I included EVERYTHING I can think of (file uploads and screenshot)
