If your LSPDFR is crashing here is the fix:
Go to your GTA main directory then in your LSPDFR folder, now open LSPDFR.ini and in the 4th line you'll find
WorldEvents.MaxNumberOfEvents = 1 -- set these to 0
save the file and close it
Now first open GTA without Rage and when your Game is loaded then open rage 🙂
hope it'll help, I had the same problem a few Months ago 🙂
let me if it's still crashing
