After Effects crash - won't start

[daveb2288848]

Hi,

Using After Effects on Windows 10. Both up-to-date.

Since last week the user has been unable to open After Effects. It crashes on start:

Event ID:100

Faulting application name: AEGPUSniffer.exe, version: 17.1.3.41, time stamp: 0x5f3b55d5
Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000

I have: 

Reinstalled AE

Reinstalled Graphics drivers (For NVidia Quadro M1200)

Reinstalled Older Graphics drivers (For NVidia Quadro M1200)

Checked no windows updates/driver updates have taken place in the last week.

I can get the program to open by disabling the NVida Quadro M1200 card completely in the device manger. But this is not ideal and causes issue for other programs.

Crash report says:

Exception Code: EXCEPTION_ACCESS_VIOLATION
Exception Parameters: User-Mode data execution prevention (DEP) violation at location 0x0000000000000000
Exception Message: 3221225477 The instruction at 0x%p referenced memory at 0x%p. The memory could not be %s.

How can I fix this?

Thanks.

Have you actually reset the configuration in the Quadro panel? Using specific application profiles can drastically lessen compatibility if certain options are enabled or disabled, trivial as some of them may seem.
