Installer crashs in VM at creation of physical volume for encryption

[Schweineschwarte]

I have an openSUSE 15.1 as the host system, Virtualbox 6.1.6 and a Xubuntu 20.04 LTS in a virtual machine, which I booted from the ISO-file.
At the installation type I chose "something else". Then I created a new partition table, then a 500MB boot-partition and for the residual space of the virtual 10GB HDD I chose "physical volume for encryption". After I set the password and clicked on OK, the the screen of Xubuntu is going black and the mousepointer shows the load-icon. After a short time I see the Log-In screen. If I log in, I see the installation was breaked up.
I expect the installation don't break up, if I create a physical volume for encryption.
