FiveM and RedM at the same time

This is a weird bug report as I’m not entirely sure the intended behaviour. Using FiveM and RedM at the same time does not work, unless you use cl2 on the one or the other. I should either be allowed to run both main clients, or cl2 shouldn’t allow me to bypass this maybe intentional block.

Client:
Canary FXServer version: 6683

What you expected to happen
To be able to use both FiveM and RedM at the same time.
Or not be able to use cl2 to bypass normal (?) behaviour

What actually happens
If I try to use FiveM main and RedM main at the same time, it doesn’t load the game which I tried to load after the other. I see it loads something in task manager though.

Category of bug
Client

Reproducible steps, preferably with example script(s)

  1. Load RedM
  2. Attempt to load FiveM, it doesn’t work

To bypass this block…

  1. Load RedM
  2. Load FiveM with cl2 enabled
