2020 version is a little outdated, you might want to consider updating the software first, as for the logs, you will need to read and check where the Module engine stops and then read the error above it as that will give you an idea on what service caused the module engine to stop.
I also saw your other posts, the problem with that is that you are randomly looking for errors on the logs. The error you pasted is for the Agent Management Polling and has nothing to do with Module Engine stopping.
