Rocket League may crash immediately to the desktop on launch, or start with a white or black screen, or crash during gameplay if the Direct 3d Dynamically Linked Library has been copied into the Binaries folder. Some third-party applications mistakenly copy this file to that location. Deleting the Direct 3d file often fixes the crashing and white screen issue.
You will need to find the folder where Steam is installed, then navigate to the Binaries/Win32 folder and delete the d3d9.dll file. Below are instructions on how to delete the d3d9.dll file from a standard installation of Steam. If you have installed Steam to a custom location steps 2 through 4 will require going to the customer locations.
To delete the d3d9.dll file do the following:
- Click on the folder icon in the lower left corner of the screen
This will open File Explorer
- Click on Local Disk (C:) in the left-hand column
- Double click on Program Files (x86)
- Double click on Steam
- Double click on steamapps
- Double click on common
- Double click on rocketleague
- Double click on Binaries
- Double click on Win32
- Right click on d3d9.dll
- Select Delete
Try starting Rocket League again
If you are not able to find the d3d9.dll file in step 10, try Deleting the Rocket League Cache.
