.qmd file disappeared ?

I've got a qmd notebook that seems to have vanished. The associated files folder is still there, along with the .html output and other files I edited on the same day two weeks ago in the same folder. I’m on a Mac. It’s not in my trash. It was in a folder that used to be linked to sharepoint but was no longer connected.

I did pull up the version of the folder in sharepoint from the last time it synced, months ago. The qmd file is similarly missing there too!

I updated to Sonoma last week, not sure if that could have anything to do with it.

Are there any known bugs? Also I tried rsrecovr::recovr(project_path = "all"), but no files were recovered.

Thanks in advance for any advice.
