I have a super weird issue which I've been trying to investigate for hours now. When I attempt to open VirtualBox on a Windows 10 host, nothing happens. A couple of VirtualBox processes appear in Task Manager but no GUI opens.
I've tried reinstalling; rebooting; installing several different versions; manually deleting all registry keys related to VirtualBox; running as administrator... nothing works. It worked fine for months but suddenly doesn't anymore.
I'm absolutely stumped so the only other thing I can do is try and look at logs to understand what's going on.
Windows Event Viewer doesn't have any relevant events to show so I was hoping that VirtualBox itself has log files somewhere. Where can I find them?

(for “Move”); the cursor should turn into a compass rose (i.e., a ‘+’ sign with four arrows). Press the “Left” / “Down” / “Up” / “Right” (cursor movement) keys a bunch of times. If the window appears, move it where you want it and press “Enter”. If nothing visible happens, give up and press “Esc”.
