Export Error -1609629695 with Lumetri Adjustments After 25.2.1 Update (CUDA Only)

Hi all,

After updating to Premiere Pro 25.2.1 (Build 2), I'm encountering the "Error code -1609629695" during export. The issue occurs specifically when using Lumetri Color adjustments and CUDA rendering.

System Specs:

• Laptop: Alienware x17 R2

• OS: Windows 11 Pro

• CPU: Intel Core i9-12900HK @ 2.50 GHz

• GPU: NVIDIA GeForce RTX 3080 Ti Laptop GPU

• RAM: 64 GB

• Driver: NVIDIA Studio Driver 576.02

What I've Tried:

• Switching from CUDA to OpenCL allows export without error.

• Cleared media cache – no effect.

• Updated NVIDIA drivers – already current.

• Narrowed it down to Lumetri Color:

  • Applying a Log-to-Rec709 LUT in the "Creative" section works fine.

  • Any manual adjustments (exposure, contrast, curves, etc.) trigger the error.

• No other effects applied.

• Same error occurs when exporting through Media Encoder.

• Tested with a very short clip, so it's not a system resource issue.

Full Error Message:

Would really appreciate any insight or confirmation if others are seeing this as well. It feels like a regression with Lumetri + CUDA on this latest update.

Thanks!
