I have one 2019 Server that fails to install any Cumulative updates with error 2024-08 Cumulative Update for Windows Server 2019 (1809) for x64-based Systems (KB5041578) - Error 0x800f0988. The whole process looks normal it goes all the way to 100% then triggers this error. This is a Hyper-V host so not sure if that can be related to any of the components.
