So since the new patch that got updated few days ago, I've been unable to open R6 for any reason. I've updated Steam, I've updated Uplay, I've updated my PC, I've even uninstalled and reinstalled the game and it still won't open. Anyone else having the same problem? Anyone knows how to get in touch with the dev team? I just bought the premium battle pass and its pissing me off I can't run it because I really like those Blacksmith skins

Hey, ReilandDarc!

Welcome to the forums. I have seen similar reports from other users on the forums and they have advised the game was being blocked by Bitdefender. Here's how to fix it:

-Launch Bitdefender
-Click Settings
-Click exclusions
-Click add exclusions
-Add rainbowsix.exe

If you have Bitdefender please try the above steps. If you do not have Bitdefender or the issue persists please try the following:

Run the game with ADMINISTRATOR RIGHTS.

Verify your game files.
It is possible that the installation of your game is faulty. To fix this, please verify your game files:

UPLAY
EPIC GAMES LAUNCHER
STEAM

Disable Background Applications.

Make sure your OPERATING SYSTEM is UP TO DATE.

Reinstall Uplay.

Update your GPU Drivers:

AMD
NVIDIA

Should the issues persist after completing the above steps, please GET IN TOUCH, attaching DXDIAG and MSINFO reports to your SUPPORT CASE.

Thank you.
