After Reinstall: Virtuoso loses connection regularly

[SymPitch]

Since I reset my PC a few days ago and reinstalled ICUE, the Virtuoso constantly loses the connection. I am sitting 1m away from the receiver on the PC but every hour at least 1 time it loses connection for a few seconds so LEDs on the microphone and USB receiver go off and then reconnects. It is not the sleep mode. Sometimes it loses connection completely so both the USB stick receiver and the microphone light flash red. 
I also feel that the range is reduced compared to before.
Everything is on the latest firmware: 
Virtuoso: v. 0.17.149
USB Receiver: v. 0.16.80
ICUE: v. 5.5.134
