Mongod process fails to start (status=4/ILL) - processor compatibility issues

[solaechea]

While trying to run this project on my current laptop which has a procesor AMD Ryzen 7 5700U, the mongod service didn't start, it fails with an error like this:

root@ubuntu-bionic:/home/vagrant# sudo systemctl status mongod

After some investigation and trying several MongoDb versions, there is a compatibility issue between recent versions of MongoDB and some Processors, the solution in my case was to downgrade MongoDB to version 4.4.
