Here, installed again 3.2.1 and same issue, would not load, uninstalled and reinstalled 3.2, works great.
Many thanks for that information, I managed to find the issue. It's when you have a user defined algorithm with the same name as a predefined algorithm (for example you added Skein, but that one is already included).
A correction will be available in version 3.2.2 that is planned to be available within the next 12h.
