Microsoft investigates OneDrive issue causing macOS app freezes

Microsoft is investigating a OneDrive issue on macOS Sequoia (macOS 15) that causes applications to freeze when opening or saving files in Desktop or Documents; as a workaround, users should force-quit the OpenAndSavePanelService via Activity Monitor, restart OneDrive, and save/open files from other locations. The company also notes an ongoing problem where some users cannot find known files and advises manually browsing to them or re-saving to improve discoverability, while reminding that a previous conflict error between App Store and standalone OneDrive builds has been fixed.
