Yes, exactly.

Uninstall Hyper-V, it's stealing exclusively your VT-x capabilities.
The trick with VT-x is that it
has to be shared, since it's "only one" available slot for its use. For example, VMware and VirtualBox do not use VT-x at the same time, but rather take turns. To put it simply, every program that uses VT-x should do this: VT-x lock, execute, VT-x unlock. This way other processes can use VT-x in turns.
On the other hand, Hyper-V
permanently takes over VT-x and doesn't let anyone else use it. If a program uses VT-x from the moment it is loaded, and doesn't let go till the moment it dies, you have a problem. So, please complain to Microsoft about that.
