Guest freezes until there is a keyboard input on Windows version

Windows guests are freezing and waiting for keyboard input and it continues to function after I press a key. I am using Windows10 Home and below is the command I use to run the guest. I have suspected if this is caused by random entropy but even with mouse moving it gives same random locks and it continues to work as soon as I press a key so maybe its not about entropy at all,
