Unable to change VM resolution

[george98]

I'm running Majaro 21.0.7 and Virtualbox 6.1.22.
I've tried mutipe VMs, and they all have the same issue, that they don't re-size to fill my monitor (wide-screen, 1920x1080).
I've search for a solution, and tried several (maxing out graphic ram, changing display to :hint" or "none", loading Guest Additions iso). Nothing changes.
I've attached the latest log file. Screenshots available if needed.
TIA

I have the same issue. The screen is tiny and I don't see how it is possible to get any work done in such a small space.
If you found a solution elsewhere, please post it here.
