Hello Ian,

I test 3 kernels available in repositories:

* 6.8.0-90-generic — no problem at all
* 6.11.0-29-generic — no problem at all
* 6.14.0-36-generic — bluetooth audio almost stops working when wifi is heavy 
loaded and recovers when downloading ends.

It may be even related to the firmware, there is difference (modinfo
rtw89_8852c shows):

filename:       
/lib/modules/6.8.0-90-generic/kernel/drivers/net/wireless/realtek/rtw89/rtw89_8852c.ko.zst
firmware:       rtw89/rtw8852c_fw.bin

filename:       
/lib/modules/6.11.0-29-generic/kernel/drivers/net/wireless/realtek/rtw89/rtw89_8852c.ko.zst
firmware:       rtw89/rtw8852c_fw.bin

filename:       
/lib/modules/6.14.0-36-generic/kernel/drivers/net/wireless/realtek/rtw89/rtw89_8852c.ko.zst
firmware:       rtw89/rtw8852c_fw-1.bin

6.14 kernel module loads different firmware binary rtw8852c_fw-1.bin
than the previous two kernels.

I also checked kernel logs (journalctl -k) and when problem happens
nothing is reported at all.
