Choose Dynamically allocated and select Next.Choose VDI (VirtualBox Disk Image) and select Next. Next, you’ll need to choose the type of file you’d like to use for the virtual hard disk.Choose the Create a virtual hard disk now option and click Create. On the next screen, you’ll need to create a new hard disk for your virtual machine.

You have two options to choose from you could either use Dynamically allocated storage which grows as you keep using the storage, or allocate a Fixed-size storage limit that offers faster performance. This portion will only be accessible to your virtual operating system, i.e., Ubuntu in this case. You’ll also need to allocate a portion of your hard disk to the virtual machine. For instance, if you have 16GB total RAM, allocate 4GB to the virtual machine. Ideally, you should choose to allocate about a fourth of your PC’s RAM.

I can also upgrade to v6.1.36 and provide the log for that crash. I think the problem started when KB5012643 and/or KB5012159 was installed but can't be sure. I've deleted and recreated the Ubuntu VM several times on both 6.1.32 and 6.1.34. I uninstalled v6.1.34, removed any files/directories related to VirtualBox. I tried starting my Ubuntu VM just as a sanity check and it crashes with a same error as amadi is seeing. I then attempted to create and install a WIn 10 VM with no success. I was using Windows 11 Hyper-V with Virtualbox v6.1.32 running Ubuntu 20 LTS without issues.

I will provide some more details on what happened to me.
