Deadlock freezes to 0 FPS after launching Discord (RTX 3060 / Ryzen 5 5600)

Hello.
I'm experiencing a serious performance issue in Deadlock.
If I launch the game while Discord is running, after some time I start getting severe freezes:

• FPS drops to 0
• The game completely locks up for 1–3 seconds
• Freezes repeat frequently
• The game becomes unplayable

Important:
Even if I close Discord after the freezes start, the issue does NOT go away.
Only restarting the game (and sometimes even rebooting the PC) fixes it.
I do not have this issue in any other games — my system is otherwise stable.

My specs:

• RTX 3060
• Ryzen 5 5600
• 32 GB RAM
• Windows 10

What I’ve tried:

• Reinstalled Discord
• Reinstalled the game
• Verified game files
• Updated NVIDIA drivers
• Disabled Discord overlay

The issue persists.

It looks like some kind of conflict between Deadlock and Discord that destabilizes the rendering pipeline.
Any advice or confirmation whether this is a known issue would be appreciated.
