I also attached my VirtualBox v7.0.6 logs in a zip file from my updated activated 64-bit W10 Pro 22H2 host PC (didn't get today's updates yet). Also, this issue had been happening for many months.

Thank you for reading and hopefully answering soon.

Are you pulling some nasty networking hack inside the VM?02:38:25.257746 NAT: DHCP offered IP address 10.0.2.15

Nope. Just using its default NAT setup (192.168.1.x). The only hack was to install W11 from local Win11_22H2_English_x64.iso file. I don't see how that's network related.mpack wrote:The guest OS is locking up, as distinct from the VM which seems to be fine.Are you pulling some nasty networking hack inside the VM?02:38:25.257746 NAT: DHCP offered IP address 10.0.2.15

I was using VBoxSVGA and no 3D acceleration in my 64-bit W11 VM. So I enabled 3D acceleration and retried. No crashes so far! And faster! I can't remember if I disabled it or if VB disabled it by default.Tronmch2 wrote:The defect tracker is 1/3 issues with the Win11 video drivers in one form or another. It appears that if you go into the display settings and enable 3d acceleration, it'll start up... And give you a TON of graphic artifacts. In my case, NOTEPAD is a black screen... Seriously, WTF is Notepad doing using 3d effects? The start button context menu is completely transparent, so I hope you use a BRIGHT desktop background...
Windows 10 in a VM with 3D enabled had the same thing. The workaround is to disable Transparency Effects in the 10 OS. Probably the same for 11.Tronmch2 wrote:if you go into the display settings and enable 3d acceleration, it'll start up... And give you a TON of graphic artifacts.

In my non-activated 64-bit W10 Pro VM, it exists.scottgus1 wrote:The "Ease of Access" path is supposed to be available on non-activated 10. Could you confirm this for us, please?
I never had graphics issue in my W11 VM. I just had hard lock ups. Turning on 3D acceleration seems to fix my random W11's lock up issue.scottgus1 wrote:Great, thanks for letting us know! Did turning it off clear up the graphics issues?
