In the error logs:
It seems that your hardware doesn’t meet the requirements of mongodb and can only install versions below
4.2
.So installing mongodb
4.2
or below will be helpful, I think 🙂What is the data directory you are trying to start the mongo instance with.If the data directory already contains files ( probably from previous 4.0 version ) , try with a different data directory path to see if the issue still persists.
