Hello,
For whatever reason I only have this problem on my desktop version of Anki. I tried looking up how to fix it, but I haven’t found anything online and I have no idea if I messed with some sort of option, but whenever I try and check my previous card information during reviews, I get this error.
I also get a similar error when I try and look at card information in my browser.
Current card during study works just fine.
I tried testing this on my laptop to see if it was a synced profile feature of some kind, but it isn’t, as it works fine on my laptop. I’m using the latest version of Anki on Windows when this happens.
