LSPDFR 0.4 is very stable. The error/crashes are on your end. I mean, we all downloaded and installed the same file. If mine is working, yours should work as well. The only one rushed here is you by rushing the installation :P.
-Make sure you activate "force borderless / windowed resolution" in RageHook plugin.
-Make sure all your files such as ScripthookV are up to date.
*Try starting RagePlugin with the mods once GTA V is loaded.
