[2021] Constant crashing after 5-10 minutes of gameplay

Hello everyone, thank you for posting about the crashing issues you have experienced.

I too experienced some crashes in the game after an update, but managed to fix this by lowering one of my graphic settings (I believe it was Clutter effects) in the games menu, I use an Asus Strix 3070. Later after another update, I was able to return this setting to its highest without crashes.

This is one of the steps I would recommend trying, as well as the following >

- Verify the game's installation files, through the game launcher, to fix any corrupt or missing files that may be causing the crashes
 
- Run the game as an administrator via the game's .exe file, right-click on the file, select Properties, select the Security tab, check to make sure the current PC user has Administrator privilege's for this file, as not running as Admin can sometimes cause several problems and can stop the game from being able to save > https://www.ubisoft.com/help?article=000060505
 
- Update GPU drivers and Windows OS to latest version (Windows 10 update currently Update 21H1 - Windows 11 not currently supported)
(Updating Windows will also update any supporting software the game and launcher needs such as DirectX, Visual C++ x64 and .NET Framework 4.5)
 
- Disable all background software in Task Manager and try a clean boot/restart of your PC, in case any software is interfering with the game -

- Make sure the game is whitelisted as not a threat in your anti-virus software, in case it prevents the game from launching or connecting online
 
- Make a backup of the games config/settings file, then delete this file in case a recent change to the settings may be causing the game to crash (Changing the recommended graphics/video/monitor settings in the game, can sometimes prevent the game from launching)
 
- Install the game to another HDD or SSD drive preferably, if available. Also try installing the game on a separate hard drive as your Windows OS (Make sure to back up any game save files onto your desktop first, just in case)
 
- Temporarily use a hardware monitoring program with an onscreen overlay, to see if there is a sudden spike in your CPU or ram usage whilst playing, that causes the game to crash
 
- Do a System File Check (SFC) for any corrupted system files and a CHKDSK for any corrupted hard drives -

This support article should explain how to perform some of these solutions -
