Intermittent Copy to Clipboard Failure for Graphic Objects in Illustrator 30.1 (Windows)

Environment:

• Adobe Illustrator 30.1 (64-bit)
• Windows 10 Pro for Workstations 22H2 (19045.6456)
• NVIDIA Quadro P4000
• Reproduced on two separate Dell Precision 7820 workstations with identical behavior

Issue:

Since an Illustrator update around late 2025, Copy to Clipboard intermittently fails for graphic objects.

Symptoms:

• Text objects copy and paste correctly 100% of the time.
• Graphic objects (even a simple line, rectangle, or ellipse with no effects, transparency, masks, or appearance attributes) fail to copy approximately 50% of the time.
• When the failure occurs, Edit > Paste becomes unavailable in Illustrator.
• Other applications (Photoshop, InDesign, Word, Acrobat, etc.) do not receive any new clipboard content.
• Repeatedly pressing Copy (sometimes 10–30 times) eventually succeeds, after which Paste becomes available again.

Additional observations:

• The issue occurs in both existing and newly created documents.
• The issue is independent of object complexity.
• The issue is reproducible on two separate Windows workstations.
• The issue does not occur on macOS with the same files and workflow.
• GPU Performance ON/OFF does not change the behavior.
• Windows Clipboard History ON/OFF does not change the behavior.
• The problem occurs whether Copy is triggered via Ctrl+C or Edit > Copy.

Expected result:
Selected graphic objects should always be copied to the system clipboard.

Actual result:
Graphic objects are intermittently not transferred to the clipboard, while text objects continue to work normally.
