I had the same issue, what I did is to uninstall LXQt and install Plasma KDE. IDK why this fixed it.
I still have this issue on NixOS 24.05 using the latest kernel and disabling power to the bluetooth chipset.
Linux trystero 6.9.6 #1-NixOS SMP PREEMPT_DYNAMIC Fri Jun 21 12:40:40 UTC 2024 x86_64 GNU/Linux
Have you tried kernel 6.6? That worked for me until I swapped out my wifi card.
This is now fixed as of kernel 6.10.x
