Default [q] bluestack black screen after opening solution

Hi guys,

I've been using bluestacks for about 1 year and I faced not a single damn problem with it. For the last 1-2 weeks, I've started noticing that my bluestacks had been lagging like hell, whenever I type anything on whatsapp or send any message, it doesn't get typed instantly. Instead it gets typed after 30-60 seconds and for the last 4-5 days I simple can't open bluestacks, it opens on windows as black screen only and nothing else. I tried restarting it but still no help, I even uninstalled several apps to make my computer RAM clear but still it won't work, I even uninstalled bluestacks, cleaned by system through ccleaner and again reinstalled it, but still the problem persists. I've even tried to open spearate apps like whatsapp from my apps option in my computer and my whatsapp even got opened as it had my last seen of today at 01:19 PM but it opened only as a black screen. Please guys as I've got to open whatsapp as I have many important people's contacts to chat with and I got to take the backup of the conversation, contacts, media and every single goddamn thing from whatsapp and bluestacks to my phone, please please please help _/\_

PS :- I've even uploaded some screenshot of bluestacks for ur better requirements to solve the issue
