I have had issues when it was copied from an old hard drive where the files were downloaded by another account name. Windows knows the account IDs don’t match so your permissions are limited. If you don’t like command line you can often go into properties , security, advanced, then use take ownership option, or select user name and check the full control option
It was an old download but it’s weird because everything else in the folder deleted except that single file.
