I can't log in

it says Invalid credentials 

my file is almost empty 

i can't create mojang account cause it boots me from the site into minecraft.net

the profile of minecraft.net gives 0 information 

the launcher of Java Edition looks like the older version than it is now 

and im not sure if thats because windows 10 edition has that launcher only 

but when i go to the launcher i cannot open anything i see logs the versions and before i do anything it instantly brings me into log in 

pressing 'forgot your password' or 'which do i use?' only sends me to minecraft.net full of useless information

why does xbox have anything to do with mojang official? why everything changed?

WHY CAN'T I LOG IN??
