For me, Obsidian started to silently and (seemingly) randomly replace the whole content of a note with the content of another random note. This has been happening to other people as well for some time now [1].
What makes this issue really terrifying is its silent nature. I only noticed one of the notes having had its content replaced while casually exploring my library.
It took me an hour to restore the original content, which I only managed to do thanks to a (very obscure) macOS feature that keeps versions of most text files. It is only possible to see these versions when opening the file (in this case, the note) in TextEdit. I haven't found another place in the UI where these versions are exposed, which is yet another interesting thing I did not know about the OS I have been using for years now. I wonder why Apple does not expose this feature in the right click menu in Finder, for example.
In any case, as much as I love Obsidian I have been rarely and cautiously using it since this happened. File safety is the bare minimum requirement, so I cannot recommend Obsidian as it is right now.

What sync method are you using?
I have my vault saved in iCloud Drive and solely access it from a single device.
We all know about iCloud Drive being known for being somewhat unreliable and sometimes causing sync issues, but I don't really see this type of bug being caused by it. I would be more suspecting if files were corrupted or changed in some other form than being replaced by other notes' contents.
The kind of issue points to Obsidian as the cause to me. Some commenters in the discussion I linked were hypothesizng about some kind of race condition or rare bug when opening two different notes in the same Obsidian window/tab in sequence and suggested using an extension that works by opening each note in a new tab, which I haven't tried. I try to work with as few extensions as possible to reduce any kind of attack risk.
I am very open to help or different interpretations of what I experienced though.
Make sure to set your Obsidian folder to "Keep downloaded" on iCloud for every device. Otherwise iCloud automatically deletes files locally to save space on your device.
It's a terrible default and Apple doesn't provide any way for developers to detect if it's off.
