Unable to set password for the MariaDB "root" user - Vagrant - vagrant

Question

I am running "Vagrant up --provision", it seems to be ok but at the end, I got an error shown below. Please help me to solve this problem as I tried many times with VPN and without VPN but getting error "Failed to start MariaDB 10.3.31 database server."
default: An error occurred while setting the password for the MariaDB administrative
default: user. This may have happened because the account already has a password, or

The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what
went wrong.```

Try to set the database username and password in the .env file of your project. Something like this:
Then execute this command: vagrant reload --provision.
I am using HeidiSQL that lets me see and edit data and structures from my VM running one of the database systems MariaDB, MySQL etc.
Hope this answer helps you.
