Serious Monterey File-sharing bug
Here's fun:
1) From a Monterey client, connect to a share on file server. Any file server. Can be a NAS, windows box, macOS file sharing - what have you.
2) Open a file on that share by double-clicking it.
3) Move that file into a subfolder.
4) Try to double-click that file again and discover that... you can't.
Relaunching the Finder/disconnecting and reconnecting the server/changing the filename or filetype will make that file openable again. Moving it back to its original location will not. It's not a permissions issue - I've been down that road at length, culminating in pulling a brand new M1 iMac out of a box and putting it next to a freshly-wiped M1 MBA, turning file sharing on on the iMac, connecting to it from the MBA, making some blank .txt files on the brand new share, and watching everything fail.
Other versions of macOS do not show the same issue when connecting to the same file share. The issue is definitely with 12.5.1, but the client who alerted me to had the issue with 12.3 so that might have issues too.
I've been in touch with AppleCare - who have been helpful but don't have any information on this. Is anyone else seeing this problem?
