Hello Alex,

We are sorry to know that.
Could you confirm whether you have disabled AVG protection and confirmed that the issue with Windows sandbox is getting resolved?
Are you using AVG Antivirus free or paid AVG Internet Security program?
In order to assist you further, we kindly request you to create your own post on our community.
It will help us to verify your account and provide further instruction.

Seriously?  The solution is to send us to another post??? As it turns out, I also have the same problem.  Since your assistance here ended on March 20 and no resolution was listed, can you please advise how you resolved this for Pawal G as it may shed some light on a resolution for me - and dare I say, Alex Trandafir?  How is "posting the solution" not part of your work flow before closing a forum query?

Hi. I have a problem with AVG Internet Security and Windows Sandbox. When AVG protection in active, Sandbox don't start. When I'm trying to start it, nothing happens. I can see only one error in Windows log:

(log translated from Polish to English, so it may not be exactly the same as in English Windows)
Name of the application causing error: WindowsSandbox.exe, version: 10.0.18362.329, timestamp: 0x51ae4091
Name of the module causing the error: ntdll.dll, version: 10.0.18362.719, timestamp: 0x64d10ee0
Exception code: 0xc0000409

Identifier of the process causing the error: 0xdc4

Full name of the package causing the error: 

Month ago or maybe two it was working without any problem. Now, to start Windows Sandbox I need to turn off AVG protection. How can I solve this problem?

I can't find which component is causing issue. I was disabling each one, but sandbox never worked. I need to disable entire AVG to make it work.
What's interesting, when I try to start sandbox when AVG is enabled, then it won't start even after disabling AVG. First I need to restart PC, then disable AVG, and after that I am able to start sandbox.

I'm using AVG antivirus free, and yes, after disabling the antivirus, Windows Sandbox it's starting.
I did not opened a new ticket as it's the same problem(avg enabled - sandbox not starting - no error shown - just in event viewer)
