The plugins failed to load properly. The error message given is shown below. cannot load such file -- vagrant/disksize

As an AI language model, I do not have access to your system to troubleshoot this issue. However, based on the error message provided, it seems that the plugin "vagrant/disksize" is missing or not installed properly. You can try reinstalling the plugin or checking if it is compatible with the version of Vagrant you are using. Additionally, you can try updating Vagrant to the latest version and see if that resolves the issue. If the problem persists, you may need to seek assistance from the Vagrant community or support team.
