Pause Menu (ESC) -> LSPDFR Tab -> Change Character -> At the bottom, select new character (blue bar). From here, you can swap or make a new character like how you made your first one.

Typically, their betas are done via their Discord server(s), especially considering the nature of the plugin.

Are you looking for liveries or models?

No, LSPDFR will only work on the legacy version of GTA. You can find out more here:

Yes, VirusTotal and other Antivirus software flag LSPDFR as a false positive because of the way it hooks into your game. Most modifications you download will flag as a false positive. If you run into this issue with Windows, you will need to add your Grand Theft Auto V folder as an exception, likewise with any other antivirus software. Here is an article to help you with adding your Grand Theft Auto V folder as an exception to Windows Defender. If you use another antivirus software, please search online on how to add exceptions.

The car pack you installed likely has a fixed livery (in simple terms, no transparent part on the livery to be painted, and/or has data values that prevent it). You can obviously change this by editing the meta flag values. In regard to your ALPRs, likely chance you need to repair the vehicle after applying the vehicle extra. It's likely extra 10-12, but I am not sure, as it's typically different especially if the vehicle is ELS.

Agreeing with Lennyy here, I originally started with QuantV's free version, switched to NVR, then NVE, and used that for the longest time. Both are performance-heavy, especially if you end up using Reshade or ENB. Though this is with using an actual PC, not a laptop, so results could vary. I am also currently using CoreFX alongside ENB (CoreFX has one, but I've made my own). I don't like paying for graphics mods, as many people don't. Needless to say, try out CoreFX with or without the ENB that they provide, and then install or modify your emergency lighting to your preference if you don't like it.

This is because the vehicle you are taking the livery from does not have the same base as the one you are trying to put it onto. You will need to find a livery that is for a base that matches the cars base you are trying to use.

Typical BCSO activities really

Both are safe to use. Reinforcing what ThinBlue said above, Virus Total flagging it is a false positive. Windows + VirusTotal will flag a lot of modifications because of the way they are modifying your game. If you ask anyone else, they will tell you to whitelist your GTA game folder because Windows flags them.
