You have exactly the same issues as before. Until we find and correct the reason for this, no amount of tinkering around in netplan nor Network Manager will help. Quite simply, the physical device, the driver and the firmware aren't happy together.

So far, searches on the internet for the errors haven't yielded anything useful.

May we see:

dmesg | grep -i -e sdio -e irmw

Is it really an error? Or is it because netplan is using networkd and not network-manager?

netplan can use either. If NM is present and running, it is almost always preferable to us NM and set netplan to defer to it.

The netplan setup is for WPA Personal network. My network is WPA2-Personal, would that cause 'Access Point: Not-Associated'?

No. Again, until we find and correct the error above, all this netplan tweaking and speculation is fruitless.

Would it be possible to completely disable on board wifi and use a USB dongle instead?

I read of problems with this chip in the Pi4 too and am thinking that to get on, I could use a dongle until the issue is resolved.

[chili555]

Aside from the possibility of a faulty device, I regret that I haven't any other suggestions.

Would it be possible to completely disable on board wifi and use a USB dongle instead?

Certainly.

[makem2]

May I ask if you will offer guidance in disabling the wifi please?
