Anki card lagging

Anki Help
1

I am currently on Anki Version ⁨23.12.1 (1a1d4d54)⁩
Python 3.9.15 Qt 6.5.3 PyQt 6.5.3

The problem starting when I downloaded the new FSRF helper add-on. There are no updates for this add-on.

Please help

Strange, FSRS helper shouldn’t interfere with the card in this manner, could you try Troubleshooting - Anki Manual

Does disabling FSRS helper remove the lag?
