fix: remove attempt to get a more comprehensive error

[martinjagodic]

Closes #7262

attempt was used to better handle the function, but it obtused the error so it was not clear which frontamtter field was duplicated.

The collection list view now displays the error toast, but does not load any entries if one is corrupted. A fix should be somewhere in backend.ts. formattedEntries and filteredEntries should return the non-corrupted entries, but still trigger the error.
