VirtualBox crashes half the time I use it (fault in Qt5GuiVBox.dll)

Post by NICKNAMENICKNAME »

When launching "C:\Program Files\Oracle\VirtualBox\VirtualBox.exe" from the desktop short-cut, 50% (yes 50%) of the time the window appears briefly then exits. However, if I immediately repeat then it works OK.

The EventLog shows:

Faulting application name: VirtualBox.exe, version: 6.1.28.47628, time stamp: 0x616db42a

Any reason why this is the case?

I'm not aware of anyone else reporting similar problems, so consider any third party apps you have installed on your host that might filter network paths etc.

Thank you for your reply.

I don't have any third party apps installed on my host that might filter network paths.

It is peculiar how this fails exactly 50% of the time.

Another thing to look at is any graphics-oriented software, since the module that fails is "Qt5GuiVBox.dll", which could be graphics related.

I'm getting the EXACT same crash. Since the last update. I haven't updated anything else. Windows 10 Pro / 21H1

NICKNAME^2 has not reported back if there are graphics-oriented programs on their PC that might be interfering.

ElderBoy15, please consider my posts above and see if you have anything that would interfere.

Also, consider rolling back to 6.1.26 and see if the problem stops. https://www.virtualbox.org/wiki/Download_Old_Builds_6_1

If you do roll back to 6.1.26 and it works please post here to say it fixed it and log a bug so the devs can look at it.

Thank you for replies. I have no graphics oriented applications on this PC (e.g. I don't use games or apps like Illustrator).

The problem remains, I also experience the same problem with earlier releases. The problem remains and is not fixed.

Happy to provide any more logs if necessary,

Please reproduce the issue and provide a zip file containing the contents of C:\Users\<username>\.VirtualBox (note the ".").

Thanks for the logs. Unfortunately, they didn't tell me more than I've already seen in 20666.

Is there anything special about the contents of the VirtualBox Manager window (8 VMs are pretty normal)?

Regarding the 50 %: If you start the VirtualBox Manager 8 times in a row, does the crash happen 4 times, or only once?

Thanks for the reply.

VB Manager crashes normally the first time I used it after turning the PC on, on second immediate attempt it loads OK. 3rd attempt straight after it works. However, if I don't use it for a while, e.g. 1 hour (without any system restart) it will crash and then be OK on second time.

There's nothing unusual about my manager window.

Please try if VirtualBox 6.1.30 exhibits the same issue on your host.

Same issue for me using VB version 6.1.32. Just started for no apparent reason. Reinstalling or downgrading don't seem to fix. I can always start 100% of the time if I run As Administrator. To be clear, this is just the VB Selection Window crashing and not the VMs themselves.
