XOrg fails to present in Virtualbox 6.1 using 2021-01-20 ISO

Using Community XFCE ISO's. The last ISO release (2020-11-28) works perfectly on boot up in VirtualBox 6.1.

I went to try the 2021-01-15 release ISO. The disk image would boot up. However, failures (red text) would appear post open-rc before switching to X. It scrolls past and I can't get back these details. The resultant XOrg output is a black screen.

I then noticed that a newer release was available (2021-01-20). After downloading and running I get the same problem - some red text indicating errors and a black XOrg output.

I'm downloading the 2021-01-20 official release now to see if this problem is w/ XFCE or distribution.

I'm open to suggestions to triage/diagnose.

Problem appears isolated to the XFCE Community release.

XOrg and desktop pops up using the Official release. There is some noise in the console output about power save daemon and virtualbox driver but the desktop does appear.
