andman24 I have the same problem, using Q3 with just a Keon. Connected VIA bluetooth to DEOVR directly (no phone app). Similar behavior, it will seemingly just drop straight back to the home. This has happened when I was doing nothing other than watching, since I thought maybe it was a weird issue with one of the new binds or shortcuts, but no it's crashed without any input.
I decided to check the forums out, frankly I figured a lot of folks would be having/reporting this issue - but it seems like it's maybe limited to folks using Meta device, DEOVR on the device and with a Keon (or other device). So, please don't ignore this and brush it off like it's only two people, If it was even four reporting it I never would have went through the trouble to make an account/post. Thanks and good luck, this feels like it'd be annoying AF to try and fix =/ but hopefully easy enough to reproduce, no pun intended.
