You're Windows Update client components are corrupted. If the following does/did not resolve it, you will most likely need to do a wipe and reload.
1. Run DISM/SFC: https://aka.ms/DISMSFC - If it still fails move to 2.
2. Reset WU client: https://aka.ms/WUReset - If it still fails, move to 3.
3. Run an in-place upgrade/repair using the most current ISO of the same build. If it still fails, move to 4.
4. Perform a PC Reset. If it still fails, you will need to perform a clean install.
