I am using virtual box to run the endless os on my dell laptop which is running on edubuntu 24.10. We are facing very strange issue! The OS loads fine but some applications (I think the native ones) do not load the content properly. The animals app does not show any text but you can just click on placeholders and content changes but no text at all. I tried uninstalling/installing the apps again but no effect. The science snacks app loads fine without issues but issue seems to be with many apps like the Biology app displays the content but oddly misses out on “i” and “l” letters! Same with Maths app!

Did you try running endless in live “Try” mode?
You could try enabling (or disabling) 3D acceleration for the virtual machine in Virtualbox’s settings.
