(SOLVED) The issue with the game crashing has been resolved. All I did to fix the issue was uninstalling LSPDFR from my main GTA 5 game directory before simply reinstalling it back into the main game directory. I want to thank the forums and members of this community for attempting to help me fix my game issues. Hopefully, this simple fix in my specific scenario solves a lot of other similar issues in the future for other people.
