Try removing the conexant drivers again and then download the 20h2 iso and try updating from it, I did like this and it successfully completed the update and after updating I reinstalled the conexant drivers again and it worked with no problem
Updating to Windows 10 Version 2004/Conexant Drivers
So what do people with computers with Conexant drivers do? Windows Update says update drivers but there are none acceptable, it also says Microsoft is working on a fix ? So what do we do? If there are compatible drivers for devices using Conexant Audio where are they, how do we get them and install or replace them (I have tried everything to no avail). When does MS expect a fix ? Are persons with Conexant audio drivers computers at end of life ? Does anybody care ?

2021-07-24T14:46:19+00:00 Hi,
I followed the instructions above by uninstalling and deleting the Conexant driver and files, then ran WU. The Windows 10, version 20H2 feature appeared and the process indicated that everything was ready. Unfortunately, the update failed to install with error code 0xc1900223.
I rebooted and the Conexant drivers were reinstalled. Uninstalled and deleted again, then rebooted and tried WU. Now, the 20H2 update no longer appears and I am still on 1909.
Has anyone seen this problem?
I am wondering whether to use the Windows Update Assistant, although this indicates that it will upgrade to 21H1.
Thanks in advance for any assistance.

I'm about to find out if this is accurate, I am not being offered the update with my laptop so I'm about to try it , using the update assistant.
I'll let you know how it goes, it's never worked in the past it has always failed and rolled back to 1909.

2021-05-06T15:55:42+00:00 An update to the problematic Conexant driver on my ASUS ZenBook UX305FA finally appeared on the ASUS website. Better a year late than never I guess. The driver from 2015 (8.66.77.57) was replaced with (8.66.95.70). Perhaps they have updated the drivers for other ASUS models as well...

2021-04-28T11:03:57+00:00 I managed to update my Lenovo G510 Type 80A8 to version 20H2, following the advice of user howardagoldberg:
I uninstalled the Conexant sound drivers (Conexant Smartaudio HD) by checking the 'Remove the driver software for this device' box. Without rebooting, I upgraded without problems using the Windows 10 Upgrade Wizard. The same version of the audio driver (8.66.16.50) remains. Everything works perfectly.
