Arbitrary change of types

I’m sorry if I failed to explain myself.

The format of my list is precisely that

esempio:
  - "[[path/a|]]"
  - "[[path/b]]"
  - "[[path/c]]"

I also verified on an old file, up to 3 months ago it worked, today opening it gave error, yet the format is the one that 3 months ago obsidian accepted and that you also confirmed to me to be correct.
I checked the updates. Obsidian seems to be installed. I’ve also done the plugin updates for that vault, I hadn’t thought of that, and even after reopening it still gives error
