First of all I would highly recommend you to upgrade at least to the latest patchlevel 3.18 P034_JANUARY-2026 as you are using a really old patch with P014_NOVEMBER-2022. Additionally you must be aware that our current supported versions are 3.19, 3.20 and 3.21.
That said, this specific OMS+ error code could be related to a bad S7DOS installation. To fix that you should completely uninstall WinCC OA and reinstall it. If it does not work (with the latest patch either) it could be that you might have to remove S7DOS entries from the registry.
