Red dead redemption 2 fail to download pc

I've been in contact with R* support for the past two months having them to try and resolve the launching problems I'm having with RDR2. It's been wildly unsuccessful so far. Which is why I reach out to the community!

It's been that I can't get the game to launch, whether it be from R* games launcher crashing, or R* saying my social club account doesn't own the game.
The three main errors are as follows:

Executing from R* launcher: R* launcher crashes and gives "The Rockstar Games Launcher exited unexpectedly. Please visit https://support.rockstargames.comfor more information."
Executing RDR2.exe directly: R* launcher gives "This Social Club account doesn't own RDR2, please ensure you are using the correct account and try again"
Executing from steam: R* launcher crashes and gives "Unable to launch game, please verify your game data"

It is my hope that someone else has experienced and solved this problem, such that I might be privy to the wonders of the solution as well.

Current troubleshooting steps attempted

• Updating Bios
• Updating Windows
• Updating R* Games Launcher
• Updating Graphics Drivers
• Disabling Antivirus
• Re-linking R* and steam accounts
• Verifying Game cache/reinstalling game (twice)
• Enabling administrator permissions to .exe
• Removing Overclocking software
• Installing everything on one drive, then opposite drives
• Deleting files in Temp folder

Since it's plausible to be a hardware problem, Specs:
i7-3930k (stock)
asus p9x79 pro
GTX1060 6gb
32gb gskill ram
ssd boot & hard drive RAID (everything currently installed here)

Thanks for reading, and I hope if you've had this problem, you've been able to resolve it...
