Build the engine from source code but I'm getting weird bugs, it's freezing and crashing

I have build the engine from source code without any modification and I’m getting several bugs on its interface, one of them is with the language which for some reason is mixed partially portuguese and english (My windows is Portuguese-BR)

Now the big deal is whenever my mouse hit certain parts of the menu (scalability, in this case) the engine just crashes and I get this error window (UE4-MyProject2 Editor is corrupt and will be closed):

And sometimes the engine just randomly freezes or I get Fatal Error

I have already build and rebuild the engine several times, deleted everything and build again but still get the same issues.
