Crackling noises when using bluetooth headphones and need help.

I have had this issues where sometimes bluetooth headsets have crackling noises. I thought it was was my old headphones and ignored it but recently I bought new headphones and they have the same crackling problem. I have windows on dualboot but it doesnt have that problem there.

I tried increasing the highest requested RTC interrupt frequency , reducing swappiness  and increasing the maximum watches on files using this https://wiki.archlinux.org/title/Profes … figuration guide. But nothing worked.

Here is the journalctl log where I captured just after I got those crackling noises

I think based on my understanding this is the issue from log

Basically this error is popping up when my headphones are crackling.  With my search on internet I think this log is related to unstable wifi connection. I have intel AX 210 wifi chip which includes bluetooth as well. Some times wifi disconnects and reconnects automatically. Is the wifi card faulty. But the same bluetooth crackling noises never happened on windows as much as linux.

Any idea how to fix this issue? Any help will be appreciated.
