Hey, I’ve recently moved all of my different note-types and card-types for vocabulary to one single note-type with two card-types. When I try to mark cards on AnkiDroid the application crashes with the error ‘collection not opened - An error occurred while accessing your collection.’. It works just fine on the Anki-Desktop and I’ve checked the database already. I feel like AnkiDroid can not find the new card-types to mark them, or it is looking for the old card-types, but I don’t know for sure. Is there a way to get a crash log from AnkiDroid? Here is the Debug-Info: AnkiDroid Version = 2.15.6 Android Version = 12 Manufacturer = samsung Model = SM-G975F Hardware = exynos9820 Webview User Agent = Mozilla/5.0 (Linux; Android 12; SM-G975F Build/SP1A.210812.016; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/108.0.5359.128 Mobile Safari/537.36 ACRA UUID = 9a843efe-5036-47f2-87fb-5d73737b17bf Scheduler = std2 Crash Reports Enabled = true DatabaseV2 Enabled = true ---
