Crash with FidelityFX Super Resolution 3.1 in Unreal Engine 5.4

[Pralexio]

I am experiencing an issue with the FidelityFX Super Resolution 3.1 plugin after the recent update of Unreal Engine 5.4. The engine crashes consistently when the plugin is enabled, and the following error message is displayed:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000000

Details:

• Unreal Engine Version: 5.4
• FSR Plugin Version: 3.1.0
• System Configuration:
  • Processor: Ryzen 9 5900X
  • Graphics Card: RTX 3080
  • Operating System: Windows 10

Steps to Reproduce:

1. Enable FidelityFX Super Resolution 3.1 plugin in Unreal Engine 5.4.
2. Launch Unreal Engine and try to modify a file inside a project (for me, it has actually happened only when I was editing a blueprint).
3. The engine crashes with the above error message.

Impact:

The issue prevents the use of the FSR 3.1 plugin, affecting the rendering performance of any Unreal Engine projects.

Please let me know if there are any available solutions or updates for this issue.

Thank you for your assistance.

Best regards
