Lumetri Color cannot be reliably copied using Ctrl + C in Premiere Pro 2026

Software Information
Application: Adobe Premiere Pro 2026
Operating System: Windows 11
Usage context: Long-form projects such as wedding films, documentaries, and commercial videos

Issue Description
In Adobe Premiere Pro 2026, copying Lumetri Color using the keyboard shortcut Ctrl + C behaves inconsistently and frequently fails.

Observed behavior includes:

- Ctrl + C does not reliably copy the Lumetri Color effect even when the clip is correctly selected

- Pasting to another clip has no effect or results in incorrect behavior

- The issue occurs with both standard clips and Adjustment Layers

- In some cases, only the entire clip is copied instead of the Lumetri Color effect

- The problem occurs repeatedly within the same project

Steps to Reproduce

1. Select a clip with Lumetri Color applied

2. Press Ctrl + C

3. Select another clip in the timeline

4. Press Ctrl + V

Result: Lumetri Color is not applied or does not function as expected.

Expected Behavior

- Ctrl + C should consistently copy the Lumetri Color effect

- Ctrl + V or Paste Attributes should reliably apply Lumetri Color

- The color copy workflow should perform as it did in earlier versions such as Premiere Pro 2025

Workarounds Attempted

- Using Paste Attributes (Ctrl + Alt + V) with only Lumetri Color selected

- Copying Lumetri Color directly from the Effect Controls panel

- Resetting the workspace

- Clearing the Media Cache

- Disabling GPU acceleration by switching to Software Only

- Saving and applying Lumetri presets

These methods only act as temporary workarounds and do not resolve the root issue.

Impact on Workflow

- Disrupts professional post-production workflow

- Causes significant time loss when color grading large numbers of clips

- Affects delivery deadlines for commercial projects

- Forces rollback to Premiere Pro 2025 for stable operation

Request
I kindly ask the Adobe team to:

- Confirm whether this is a known bug in Premiere Pro 2026

- Provide a fix in an upcoming update

- Improve the stability of Lumetri Color copy and paste functionality

Thank you for your time and continued support. I am happy to provide additional details if required.
