I keep getting this error, even if I disable all of my add-ons and do the “Check Database” function.

Any ideas what this is? I can only do 2-3 cards before I get this error again, and have to restart my Anki and then it does it again.

An error occurred. Please start Anki while holding down the shift key, which will temporarily disable the add-ons you have installed.

If the issue only occurs when add-ons are enabled, please use the Tools \> Add-ons menu item to disable some add-ons and restart Anki, repeating until you discover the add-on that is causing the problem.

When you’ve discovered the add-on that is causing the problem, please report the issue on the add-on support site.

> @zenitsulightning I recommend you update to the latest Anki version. You have the v3 scheduler enabled, and it was only partly complete in 2.1.44. If you’d like to remain on 2.1.44, please disable it with the latest version, then downgrade again.

Latest release is [23.10](https://github.com/ankitects/anki/releases), if add-ons are important to you, consider 2.1.66
