Error screenshot (if any)

System specifications RTX 3080, Ryzen 7 5800x. Other parts are high-end too.

Also add what you already tried so far.
I’ve tried:
Disabling my firewall and antivirus
Deleting the cache
Uninstalling Steam, Rockstar Launcher and Red Dead Redemption 2.
Installing Steam, Red Dead Redemption 2 (and playing it + online) and Rockstar launcher, in that order.
Reinstalling RedM.
Changing my DNS server to Google’s.
Adding the canary line to my CitizenFX file.
Renaming the EOSSDK-Win64-Shipping.dll file for Epic (despite having Steam, couldn’t hurt to try).
Joining many, many times. Letting it load until the pink CfxSendTo messages pop up, and then rejoining. Out of 80 or so attempts it loaded in once.

I’ve basically given up. A fix would be much appreciated.
