So my game won't start now.

So I've had this problem since around the start of the year. Whenever I try to start the game, the launcher will appear. When I click play on the launcher, it will display a pure white window for about a quarter to half a second, and kill game (confirmed by task manager). This problem happened on my old pc, and the one I built in April. Both machines are Windows 10. I looked on many other forums, and none of them helped me.

 

Solutions I've already tried:

• Reinstalling VCredist
• Verifying integrity of files
• Renaming Dungeondefenders.exe and DunDefGame.exe
• Changing resolution
• Uninstalling workshop content
• Reinstalling
• Running steam as an admin
• Running the game directly as an admin

Here's a short video demonstration.

Hi Crotorious, 

I had a similar problem with launching the game recently. Every time I pressed play on the launcher it would crash, steam would say running then not 3 seconds later. I also tried the things you have done however mine is fixed and your problem could be similar.

Do you get a crash dump in your Dungeon Defenders\Binaries\Win32 folder? It will be called something like "dundefgame_7504_crash_2019_5_29T21_15_11C0.mdmp".

I debugged mine by opening the crash dump in visual studio and running Debug with native only. It hit an access violation relating to nvcuda.dll which is Nvidia, and relating to graphics drivers. I updated my drivers and it launched after a restart.

Try updating your graphics card drivers first, and if you get a crash dump post the file here if you can, if you don't have visual studio ill debug it for you. 

Hope this helps.

I just searched the Win32 folder and the Dungeon Defenders directory (just to be safe) and couldn't find any crash files.
