In the launcher, the type of account you're using is shown like this:

This translation for German is incorrect, it should be "Microsoft-Konto", with a dash instead of a space.

However it appears that fixing this via crowdin is not possible. The translation for this is just "account" which is suffixed with a space to the word "Microsoft". Combining words like this is not correct in all languages.

The translation string should be "%1$s account" or similar, so that translators can customize how the word is combined... and even that might not work in all languages. It might make more sense to just have two separate strings for "Microsoft account" and "Mojang account".

FWIW this might also affect other strings, but I haven't hunted for those.
