Hi. I have a problem with blueprints. They just don’t open. Making game is my life. Unreal Engine was always the best and number one games maker for me. But, one day i opened blueprint, and what? Nothing. I tried my best. Deleted all my projects, deleted the engine and installed it, i have everything updated and turned off secure boot in my bios because when i’ve had it, unreal engine blueprints didn’t worked. Nothing works. 
Hey there @Piesel_TT! Welcome to the community! Does the blueprint window just not appear? In the windows tray is there a (blank) secondary entry under Unreal? Commonly when I hear issues like this, it usually means layout issues.
If possible, in editor can you go to Window > Load Layout > Default Editor Layout. This will reset your editor’s layout but if the windows locations were bugged this should correct it.
