problem with sound

Hi. I have a problem with FC26 on PC.
When I launch the game and start playing, after some time the sound completely disappears on my whole computer.

The strange thing is: as soon as I close the game, the sound immediately comes back.

I use Windows 11 and Bluetooth headphones.
This issue happens only in FC26 — all other games and apps work fine.

I already tried:

• reconnecting Bluetooth headphones
• changing default audio device
• updating audio drivers
• restarting the PC

But nothing helped.
Does anyone know how to fix this problem?
