FSRS parameters not optimizing on desktop app

Hey everyone, wondering if anyone else has run into this. Every time I try to optimize a preset on the desktop app, it goes through the calculation step but then the entire settings page crashes. None of the parameters update at all. It does work fine on the Android app, just not on desktop. Here’s the link to my reddit post, I have uploaded a recording of the same there FSRS parameters not optimizing on desktop : r/Anki
Would really appreciate any help or suggestions—thanks!

Thanks for including the link to your other post!

What about the things I suggested yesterday?

No, that’s definitely unusual. Especially that it only closes the Deck Options window, but the app seems fine.

Start with the Troubleshooting Checklist – Troubleshooting - Anki Manual . If something there doesn’t fix this, go to Help > About – click Copy Debug Info – paste that here when you respond.

Could you run Anki in the console (“anki-console.bat” in the install folder on windows) and send what it outputs after hitting the optimize button when the error occurs?
