I'm sorry to hear that you also have a problem with the update! Thank you very much for your questions, they are more like valuable suggestions to me!
1. Did this happen when you updated Mnemosyne, or when you updated to Big Sur? Or both? - Sorry, I only updated Big Sur. I use an old version of Mnemosyne (2.7). It was probably stupid of me not to try updating it first.
2. Did you try re-installing Mnemosyne with the latest version yet? - I will try doing it after the backup, I was afraid to lose my progress, I have 4.5k cards there. I will back up them and then I will try to reinstall. The last time I moved from a machine to
machine, it marked 5 hundred cards as yet-to-learn, so I try to avoid
doing reinstall : ) (technically a "move" from a computer to a newer computer is like reinstallation of a program in some aspects, I guess...)
3. What happens when you try to view the graphs? - it works. A bit slow, it makes a pause for a second, but it is exactly like before the Big Sir's update.
4. Is there any way to get an error message from the crash? - I will try to get it asap!
Sorry, I have a new question: is there a way to activate all my cards except for through the study menu or "command+d"?
With best regards, S
