Can't preview AR6 thumbnails running Windows 10

[MAB]

Could be an option reset after a Windows update or something else that caused a change in the folder settings. Get to the 'folder options' by whatever means, I am using Windows 11 now but I think it may be in 'view' on the File folder open window menu. Make sure 'Always show icons, never thumbnails' or something similar is NOT checked off. Check through all the folder settings but do not change anything if you are not sure what it will do... unless you write down any changes so you can revert back to the original settings if need be.
