Fixing the crash at startup.

To fix this please first re-run the setup tasks specific for you IDE, you may need to close and repoen the project for your IDE to take note of the changes. If this fails please keep reading.

If you are using Intelijj open the run configuration panel and delete the 2 run configs for the client and the server and then re-run the setup. This should generate new run configs, again you may need to close/open for the changes to take effect.

For vscode and eclipse delete the run config files and re-run setup.

This will only need to be done once, this change has been done to ensure it never needs to be done again in the future. If you still need help please reach out on the discord or irc servers.
