How to fix Rainbow Six Siege crashing?

First, perform some initial checks and quick fixes:

Check the system requirements: If you want to play R6S without interruptions and with a decent FPS, your PC must meet at least the minimum requirements for Rainbow Six Siege.

Right-click on Tom Clancy’s Rainbow Six® Siege and select Properties.
Navigate to the Local Files tab, and click on Verify integrity of the game files.

Ubisoft Connect:

Launch Ubisoft Connect and click on the Games tab.
Right-click on Tom Clancy’s Rainbow Six® Siege and select View game details.

Epic Games:

Right-click on Tom Clancy’s Rainbow Six® Siege and select Manage.
Click the Verify button.

Time needed: 5 minutes

This critical process must be done regularly to avoid game issues like Rainbow Six Siege crashing. The graphics driver can be updated manually or automatically through the Device Manager.

Click on the Windows icon, type Device Manager, and open it.
Double-click on the Display Adapters section.
Right-click on your GPU and select the Update driver option.
Select the Search automatically for drivers option.

3. Allow R6S through the Firewall

Windows Firewall is a critical security feature and should always be enabled. However, if you experience problems with R6S crashes, add Rainbow Six Siege as an exception.

Click on the Windows icon, type Windows Defender Firewall, and open it.
Click on Allow an app or feature through Windows Defender Firewall.
Click on Change Settings and Allow Another App.
Select Browse, and navigate to the Rainbow Six Siege installation folder.
The installation folder will most likely be within the game folder of your game distribution platform.
Click on the Rainbow Six Siege executable file (.exe) and select Open.
Check the checkbox in columns Private and Public in the Rainbow Six Siege row and hit OK.
Restart your PC.

4. Clear cache files

R6S and your game distribution platform (Steam, Ubisoft Connect, or Epic Games) store temporary cache files on your PC. These files are helpful, but if they cause game crashes, the best is to clear them.

Use the Windows Key + R shortcut to open the Run dialog, type %localappdata%, and hit OK.
Press CTRL + A to select all files in the folder.
Hit the Delete key to delete all the files in the folder.
➡ If prompted to confirm, click on Yes.
➡ If some files can’t be deleted, click on Skip.

Extra steps

If you still experience difficulty playing R6S due to the game’s stability, try to:

🛡 Temporarily disable antivirus: Another software that might recognize R6S as a threat is your antivirus. If this turns out to be accurate, add the game to the whitelist and re-enable the antivirus.
💻 Disable fullscreen optimizations: Fullscreen optimizations boost performance and prevent crashes. However, many players noticed that disabling them stopped R6S from crashing.
⬆ Update your Windows: Click on the Windows icon, type check for updates, and open these system settings. If any Windows components are outdated, download them and restart your PC.
