How can I recover files from OneDrive after an error on MacBook?

I have a persistent error message when i log in to my computer "“OneDrive” is damaged and can’t be opened. You should move it to the Bin".

- if I do this, will I lose all the files I have in my One Drive or are they safely in the cloud and I just need to download a fresh copy of the App?
