I have the same issue here. Bought headset a week ago. What I noticed that if you are on Wireless and trigger on/off switch (changing to USB mode and back to Wireless) resolves the issue, but of course this is unacceptable for a headset that costs 230 EUR.
From what I've seen now it happens at least once per gaming session and not only in one game, but in each of them I played. Once it happened while speaking on Discord, while seems I haven't had an issue while watching Youtube or listening to music (Spotify).
Dongle is connected via I/O - so directly to the MB.
I guess that my software/FW is also up to date.
