Is there any way to temporarily disable d3d9on12.dll

[vdwtanner]

Hi VallEilian, a crash dump would be helpful in debugging what went wrong here. It's not clear from the call stack why device creation failed.

There is not a way to disable 9on12 aside from installing a device with a native d3d9 driver (Alderlake devices do not have a native 9 driver by design).

Here are two typical dumps that I have collected，they come from different users
7.9.7_7312724087921623042.dmp
7.9.7_7311171171852091393.dmp

Is there have any progress on this issue? The number of the crash we have discovered online is gradually increasing
