Review Error "name hp not defined"

This error comes up every 2-3 cards. Yesterday i added the ‘AJT RefoldEase’ and the ‘Pass/Fail 2: Remove the “Easy” and “Hard” buttons’ add-ons. And today when I do the reviews this error shows up, even after I deleted those two add-ons the error still shows up. And after I click the OK button when the error shows up, it automatically skip to the next card, which I don’t know if the review I made before the error shows up is available, what should I do?

Still looks like an add-on problem, then

Please close Anki, then open it in safe mode by holding down the Shift key while starting Anki. Keep holding Shift down until the on-screen message informs you that Anki has started in safe mode.

If the problem goes away, that indicates an add-on is causing the problem. Remove any add-ons you don’t need, and disable half of the others. If the problem continues, try the other half. Repeat the process until you’ve figured out which add-on is causing the problem. Then please report the issue to the add-on author, using the Copy Debug Info button, and pasting that into the report.

It’s definitely add-on related. I can’t find that text string anywhere in Anki’s code.
