Im danish so dont comment on my english.
Well i’ve had a problem with the Infinity loadscreen in RedM my self and i’ve bought the game on epic games. (this Fix might also work on steam)
So Basicly the problem is that your RedM cant connect to your rockstar launcher bcs you cant launch both Epic games launcher and Rockstar Launcher.
Here is the steps you need to follow.
Find your Red Dead Redemption 2 folder
Find the file named EOSSDK-Win64-Shipping.dll
Rename the file to [Rename]
now just close your Red Dead Redemption 2 folder
Launch both Epic games/steam and Rockstar games launcher
Now just Run RedM and your problem should be solved.
Hope it will help you guys
