If some kind of auto synchronization is engaged, it might copy the files to the cloud, but it won't delete them from your computer.

Do you know for sure your files are in the cloud, presumably MS Onedrive? If so, you must be signed in to access them.

If they are in the cloud, there could be other reasons beyond your control as to why files cannot be accessed. For example, some critical intermediate internet server between you and MS could have malfunctioned. In which case, just try again later.

Good luck.
