Can't start my Gateway on Virtualbox : Black screen

[happy_hollaf]

Hi all,

Unfortunately my Gateway won’t start and is stuck on a black screen :

Any idea on what may cause this ? Should I optimize something in my Virtualbox ?

Thank you for your help

Looks like you have Hyper-V or Virtualization-Based Security enabled. This causes VirtualBox to break very frequently. Try following the instructions here:
