updating Chrome automatically via intune

Yes, the proper resolution is to install the Windows.admx file. You can download it from Microsoft at the links below:

Windows 10: https://www.microsoft.com/en-us/download/details.aspx?id=104677
Windows 11: https://www.microsoft.com/en-us/download/details.aspx?id=104593

Once you have downloaded the MSI, run it and define the location you want the admx files copied to. I recommend using a temporary staging folder. After the admx files have been added via the MSI, you can then go to Intune and add the Windows.admx file. After adding the Windows.admx file to Intune you can then successfully upload both the Chrome.admx and the GoogleUpdate.admx files to your template imports.

I just had this exact same issue today with the exact same error string. I followed the process I just laid out for you and I was able to get it working.

Hi
Have you tried using Winget? You can package your applications with Winget and deploy them with Intune. And you can use the Winget-AutoUpdate package to automatically update your apps.
