Null reference exception when creating script in blank project

[SjorsVanGelderen]

Just opened the editor for the first time, set plugins for everything except the option for the default editor to use with unknown file types. Then created a script, and got a null reference exception.

Log:

System.NullReferenceException: Object reference not set to an instance of an object.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
