I see your solution but my obsidan just now keeps copying itself with empty files on my desktop. It has stopped my morning plans. I am also afraid of it sync’ing to the Obsidian Sync that I just bought.
I keep getting the Obsidian is indexing your vault, and a count of 0/121 now, it was like 70 and keeps increasing. I do think this is not a support issue but a bug with what they have done to fix the mobile version of icloud to get it to work, and now the windows icloud connection is broken.
Furthermore, when you give a solution for a work around, please write it for the not so tech savvy people by giving a numbered list of what you did to save your windows obsidian vault. Just a note from someone who trained in CS for IT, once upon a time.
