So you mean your problem is not solved yet? anyway now you can see the shared folder on File explorer. Me not.
Mine is winver 26100.3476, onedrive 25.035.0223.0003 64b (insider) I tried to update as very up to date but everything is the same.
Furthermore, this bug/problem is not only about the FE sync issue. The Onedrive web also does NOT allow to Copy/Move any folder, file to(or from) Shared folder.
Could you check about yours?
It's strange, because with some other accounts, the shared folder is working very well still now.
MS PLEASE FIX THIS URGENTLY THIS MAKES EVERYTHING WRONG
Right, the problem is not solved, only changed a bit. As of today, my OS build is the same as what you list here. Through last week, my OneDrive version was the same as mentioned upthread: 25.020.0202.0001. However, as of today it has updated to 25.031.0217.0003.
Still today (same as end of last week), I can access the folders through FE, but they are 3+ weeks behind and will not update to current versions no matter how much syncing, reinstalling, disconnecting-reconnecting that I do. And files I've added in the past 3 weeks don't show up at all. It's like there's an image or something--a snapshot--of my OneDrive that is outdated and won't re-sync to update my computer.
