For a folder specified as a synced folder by cloud storage (like Google Drive, OneDrive, or Dropbox) and its subfolders and files, the context menu items provided by Bandizip and other third-party apps do not appear when you right-click on them.
This issue is due to the File Provider introduced to Mac from macOS Monterey 12.1. File Provider is a virtual file management function provided by the OS instead of cloud storage, and it makes the synced folder specified by the cloud storage exist only as a virtual folder and the path of the actual synced folder get specified by the OS.
Some functions (including Finder Sync) of the Finder are disabled in a folder synced by using the File Provider and because of that, the right-click menu provided by Bandizip and other third-party apps cannot work correctly on such a folder.
