Mouse input corrupt

Issue:

I start any round in bf 6 and shortly after the mouse input is corrupt as if I disconnect the mouse and reconnect it every few second's.

No sight movement or mouse klicks are registered.

This is then also within the menu and also in Windows 11.

Restart does not help only a full shutdown and boot clears the mouse issue.

Any other game is running fine. For example:

What I tried:

I have set the mouse pickup down to 500hz, disabled controller in Steam and disabled my ble Xbox Controller in the device manager.

Any help/ideas?

I played around 9 hours fine but suddenly this occurs.

Windows / Driver / Steam / BF6 up to date.
