Can´t open VirtualBox in Windows10

Hey together,

i use Oracle VirtualBox 5.2.22 on a Windows 10 Host.
The Problem is i only can start Oracle VirtualBox one time after installing.
When i close it then or restarting the HostComputer i cant start the tool anymore.
When i try to open it as an Administrator there just happens nothing.
I opened the TaskManager and then i see, that VirtualBox Interface and VirtualBox Manager is running.
But i dont see it anywhere and cant open it :/

Is anyone there, who have the same issues or have a way to fix this problem?
I searched allready on Google but dont find a way which helps me to fix it.

Do you have any 3rd party antivirus? Uninstall them completely (don't simply disable them) and try again...

I don´t have any 3rd Party Antivirus.
Also i deactivated the Windows Defender Fully and also i deactivated the RealTime Security of the Defender in the Registry :/

No, you do NOT have the same problem. Please open your own thread next time, unless you're 1000% sure that it's the same problem. You can't start a VM, "mafare" can't launch VirtualBox a second time. Not the same...

But, to save some time, please read really carefully the following FAQ: Diagnosing VirtualBox Hardening Issues for some generic guidelines/ideas. Remember, these are guidelines, not the exact solution, you have to use your judgement as to which program might be responsible. I would start with Symantec...
