Well I did downgrade of kernel to 5.x
using sudo rpi-update f5c4fc1
and same issue with older kernel.
So kernel is not the cause
Disabling wifi fixes errors. Now how can WiFi and bluetooth co-exist? Thanks
Setting WiFi country in
/etc/wpa_supplicant/wpa_supplicant.conf
as
country=US
and rebooting
fixed bluetooth skipping with Wi-Fi enabled. That's on 5.x kernel. I'll try on 6.x later
WiFi 2.4G and Bluetooth share a frequency band, and the WiFi and Bluetooth halves of the 43455 WiFi/BT chip share an antenna, so there is always going to be a degree of conflict between the two. USB3 radiates into the same frequency band, which makes it even worse.
Setting WiFi country in /etc/wpa_supplicant/wpa_supplicant.conf as country=US and rebooting fixed bluetooth skipping with Wi-Fi enabled.
i. What was it set to before? ii. What is the correct setting for your region? iii. Which channels are chosen with US and with the previous Country Code?
FYI my Pi 4 is doing a good job of acting as a Bluetooth audio sink for my Android phone and simultaneously streaming YouTube video (and audio) over 5G WiFi.

it was in AP mode on Pi4
That's the kind of non-standard configuration you should disclose when reporting an issue.
WiFi country was unset before.
Yeah, that's likely to cause problems.
Might be that was the fix for this one too? https://github.com/raspberrypi/linux/issues/5454
I doubt it - that user said they were on a 2.4G connection, and the new power supply seemed to fix it. Thanks for the nudge though.

Additional context
feels like regression in 6.x kernel to me. I use it on system which gets built by a script and it seems issue started with upgrade to 6.1.x kernel
