Back to the previous situation 
As soon as I unlock the wallet, it crashes because it tries to stake.
This has nothing to do with the wallet.dat file because I created a new one.
If this has to do with the size of my chunk of coins, it has to be fixed immediately.
It doesn't make sense to split my stash in thousands of small blocks.
The 2.4 wallet was working like a charm...

Im trying to find out a solution for the issue as soon as possible and if it's caused by the size i not really understand why i stake with 19m and someone else with like 200k can't.
I know the v2.4 wallet was working well but not much has changed since v2.3.1 so the code was very old still and the core really had the need for a upgrade.
