Hello everyone, specifically made account to ask question/report bug, haven't used this forum before so im sorry in advance if it's a wrong sub-forum or im not using correct formatting.

I've been using VMIX for livestreams for almost 4 years by now and did more than thousand livestreams with this software. Yet i've never encountered situation for VMIX to Cut Transition on its own into Input(how convenient that this input also stops all recordings of stream, as it is Outro Input), and it happened twice, with second time being 5 seconds after i went back into broadcast after first time, and 20-30 seconds later it also used FTB button which caused my external to turn black and mute stream.
Idk if it was what helped, just plugged out Elgato Stream Deck and finished broadcast with keyboard and mouse for 8 more minutes without issues.
Also worth pointing out, only i had access to this PC at the moment, and i wasn't even having my hands touch any input device, so missclicks are not possible, and there are no Shortcuts set up for any of those actions. It's just out of nowhere.

Question is what can possible cause anything like this?
PC Specs doesn't seem to matter as we had same setup for past 3 years.
Vmix version 29.0.0.35 x64
