Trouble with going to next Anki cards

i have been having difficulties with my anki. When i try to move to the next card, sometimes it doesn’t work at all or most of the times, it shows me the answer of the next card directly. I have followed the troubleshooting steps and remove adds-on but none of them work.

Any help will be appreciated!

The complete bug code:

Anki 25.07.5 (7172b2d2) (ao)
Python 3.13.5 Qt 6.9.1 PyQt 6.9.1
Platform: macOS-13.1-arm64-arm-64bit-Mach-O

[You posted this under add-ons, but your debug info doesn’t mention any add-ons being involved, so I moved this to general help.

You mention following the troubleshooting steps, but the solution to this is almost always #6 on that list. Are you sure you tried all of the available drivers and restarted after every switch? Troubleshooting - Anki Manual

It’s not clear if you got this debug info from an error message, what the error was, or what you were doing when it happened. For now, go through the rest of the Troubleshooting Checklist, step by step. If you can tell us exactly what you’re doing that triggers the error, and what the error says, we might be able to direct you to something more specific.
