TeamViewer crashing on iPad Pro when using VirtualBox on host

Hello,

I’m using the latest TeamViewer on iOS on my iPad Pro to control a Windows 10 PC which has the host server installed. It works great, but when I launch VirtualBox with a Lubuntu VM, it simply crashes the iOS app after ~10 seconds, then I can launch it again but if I do it too many times, TeamViewer tells me to calm down.

Any idea about why this is happening? Thanks!
