created new steam account dirt5 worked for a month or so then stopped again with same error "please help by uploading the dumpfile xxx.\dirb60d.tmp.dmp to dirt5report@codemasters.com " never got a reply have tried multiple times ...... THEY JUST DON'T CARE

the game doesnt launch fine. the game start until the first screen... when I do the first A the game crash and send a message "please help by uploading the dumpfile -'C:\users\steamuser\Temp\Dir74d.tmp.dmp' to this email : 'Dir5report@codemasters.com'
the only little detail is that I've this error in steam deck no in windows also it is supposed to be a fully verified game by Steam. anyone with this issue?

Game will no launch. I receive an error "no compatible graphics card found". My graphics card is a "AMD Radoen HD8970M" is this card suitable for this game, all my other games work fine.

Game will not launch for me either. Tried all the fixes and did all the research. I've come to the conclusion that the game is not working for Windows 10 version 1809. Codemasters, please get working on a patch for this.

salut, sur dirt 5 mon volant fanatec csr est bien reconnu par le jeu dans les paramètre, mais aucune fonction et touche ne fonctionne.

This was the solution for me.

Right-Click Dirt 5 in Steam > Manage > Browse Local Files > Right-Click "Dirt5.exe" > Compatibility > Check "Run this program as an administrator" > Click "Apply" and then "OK"

Next for Windows 10

Right-Click Taskbar Start Button > Left-Click "System" > Under "Related settings" on the right side of the System Window > Left-Click "Advanced system settings" > Left-Click the "Settings..." box under Performance > Left-Click the "Advanced" tab > Left-Click "Change..." under "Virtual memory" > Uncheck "Automatically manage paging file size for all drives" > Left-Click "Drive C:" > Left-Click "Custom size" > Set the "Initial Size" and "Maximum Size" to "4096", Left-Click "OK" > Then Restart your computer.

After I performed the above steps, I was able to launch Dirt 5 for the first time.

Still cannot launch DIRT 5 in Windows 11 Pro version 22000.795. How should I do to launch the game?
