Freeze button not working in 1.6.4 (regression from 1.5.1)

[ElBaldo1]

Hi Langflow team 👋

After updating from Langflow 1.5.1 to 1.6.4, the Freeze (and Freeze Path) button stopped working.
In 1.5.1, the feature correctly prevented components from re-running and preserved the last output state.
In 1.6.4, pressing the Freeze button has no visible effect — components still execute and refresh outputs.

Environment:

macOS (Apple M4, 2025)

Installed via uv

Tested on Chrome and Safari

Clean reinstall (no cache or saved state)

Reproduction:

Create a simple flow (Prompt → LLM → Output)

Run it once.

Click Freeze on the Prompt component.

Change the Prompt text and run again → the output updates (Freeze ignored).

Expected behavior:
The frozen component should keep its previous output and not re-execute.

Notes:

Works as expected in 1.5.1.

In 1.6.4, the button still appears, but the backend seems to ignore the frozen state.

No console or backend errors appear.

Possibly related to the recent “Fixed freeze implementation” change.

Could you confirm if this regression is known or if the freeze behavior has changed intentionally in 1.6.x?
If it’s a bug, I can provide logs or test other versions to help reproduce.

Thanks for your great work on Langflow! 🙏
