RedM Fails During Rockstar Launcher Initialization / Vulkan Memory Error – RTX 4060 Ti

RedM Client Support
1

What is the issue you’re having?

RedM consistently fails during the REDM Launcher initialization phase. In most cases, Red Dead Redemption 2 never loads at all, and often the REDM Launcher itself does not fully open. The crash or error occurs before the launcher reaches the main menu or any server connection. This issue is reproducible and occurs on a system where RedM and RDR2 previously worked without issue.

Steps to Reproduce

Launch RedM via desktop shortcut

RedM attempts to start launcher.

During this process:

The REDM Launcher either fails to open, or opens briefly and crashes.

A Vulkan memory / graphics-related error occurs before RDR2 initializes.

REDM never reaches the main menu.

This happens consistently.

Issue occurs before RDR2 gameplay or server interaction

Hey there, came to this forum to look for an answer, but for now found a “fix”?
Went into RedM, before picking a server check the settings page top right and disabled the NGui option (as it said it could be unstable so just tried). After choose a server to play and went in after trying a ton of different things! Hope this works for others!

Hello, I can’t even start REDM. When I try to launch it, this message pops up before the main interface loads. Is there a way to fix it?

Same problem here. Never had problems with windows 10 for years.
I also tried everything.
The only thing working for me sometimes is deleting the chaches. Sometimes I need 5-10 trys to start RedM. It is so weird. This is something cfx has to fix I think. It is not a problem of the Users.
