For me, the latest GTA push has caused significant issues with LSPDFR mods/plugins. First, reverting to 3509 did not work for the first time in a while. Secondly, uninstalled/reinstalled both GTA and LSPDFR several times using CJ's tutorial flow. Thirdly, using latest AB's Scripthook V and Nightly's Scripthookvdotnet, so far so good, clean versions play well together. However, as soon as I install a mod or plugin in the order suggested by CJ's 2024 tutorial (e.g., clear the way, compulite etc), when LSPDFR begins to load, the game crashes to a blackscreen/exception error etc. Fourth, I selectively uninstalled mods/plugins in reverse order to identify the potential conflict with no luck until all mods/plugins are uninstalled. Additionally, any mod (e.g. pts21) vehicle mod or malibu_mansion that is loaded into mods/update/ X64 dlcpack folder with it's own .rpf and then added to Open IV in dlclist causes issues as well.
I suppose the easy answer is most if not all mods must be updated or you must have successfully reverted, but based on the number of comments indicating issues with this new build there might be other variables at play.
