After update to MacOS Big Sur 11.7.7 desktop aliases fail to open the original folders

After the upgrade to BigSur 11.7.7. all of the folder aliases on my desktop fail to open the original folders in Finder. Similar bug to the one reported in "MacOS 11.4 Big Sur has issues with alias … - Apple Community" . My bug is slightly different. As in the bug above, double clicking on the alias fails to open the target folder, instead displaying the files for Macintosh>Users>timothychilders. But unlike the original bug report above, using a right click to 'Get Info' shows the correct path to the Original folder. And the button Select New Original... lets me click it and will let me navigate to the Original folder and select it. But after I do this the finder STILL displays the files for Macintosh>Users>timothychilders. I tried both a Shutdown, and a Restart with no change in behavior. Also tried to delete the alias on the desktop, and create a brand new alias and moved that new alias to the desktop. The new desktop alias exhibits the same behavior. A post on StackExchange>AskDifferent suggested deleting the apple.com.finder.plist from Library/Preferences and rebooting to let MacOS Finder build a new .plist. but I didn't fine apple.com.finder.plist there, even after a reboot. Any suggestions would be appreciated.
