The previous Core version used 2 years ago was 19.0.1. I have since then upgraded to 21.1 last year. The wallet which worked fine with 19.0.1 is no longer loading in 21.1. The database in up to date and the default wallet(empty wallet for 21.1) is loading fine but the previous wallet is making Core close without error messages. Also tried a few copies of same wallet with same result.
Thanks, Christian
