I use Windows and sometimes when I download a anki deck, my decks dissapear from my menu but i can se all the decks in explore The only thing that I can do is go to the backup to get my decks again on my main menu ![image](https://us1.discourse-cdn.com/flex002/uploads/anki2/original/2X/4/4e21a02f94d4bec2accf8076eacef226068dcdb4.png) ![image](https://us1.discourse-cdn.com/flex002/uploads/anki2/original/2X/8/8f65418b0f054a05fe6fedbc733d4857de29fd79.png) ---

I’m just a user. I had a similar problem once and it helped to disable the graphics acceleration.   There’s this official documentation: [https://changes.ankiweb.net/#/known-issues?id=hardware-acceleration-and-startup-issues-on-windowslinux](https://changes.ankiweb.net/#/known-issues?id=hardware-acceleration-and-startup-issues-on-windowslinux) Hardware acceleration defaults to off on Windows and Linux. Enabling it in the preferences screen and restarting Anki may make Anki’s interface more responsive, but some users may experience missing menubars, blank windows or crashes when it is enabled. On Windows if you’re unable to get to Anki’s preferences screen and restarting Anki a few times does not help, you may need to manually adjust the graphics driver. You can do this by starting cmd.exe and typing the following: ```auto echo auto > %APPDATA%\Anki2\gldriver ``` There are three settings you can try: ‘auto’, ‘angle’, and ‘software’. If you have problems both when hardware acceleration is turned on and turned off in the preferences, it’s worth giving ‘angle’ a go. I would also make sure to run the latest Anki version which is 2.1.35 at the moment.   Does this solve the problem? ---

It might be the same issue. > [@Deck list is blank](https://forums.ankiweb.net/t/deck-list-is-blank/2241/2): > > The method Anki uses to send the deck list to the web toolkit can’t cope with very large deck lists. This may be fixed in the future when a different approach is taken, but for now I’m afraid the only option is to reduce the number of decks and/or the length of the names until it starts working again. You could either split unused decks off into a separate profile with export+delete+import, or merge the child decks using [https://ankiweb.net/shared/info/113367344](https://ankiweb.net/shared/info/113367344) ---
