As mentioned, all my addons from ankihub and the buttler have disappeared for some reason. No clue how this happened. What is the fastest way to get them back?
I still have the add-ons on my other devices. The device on which the add-ons disappeared was working just fine a couple of hours ago.
You can copy your add-ons folder from another device. See this for the location of Anki data: Managing Files - Anki Manual
thank you!
