Description

Repro Rate: 10/10

This issue occurred in the live build of //UE5/Release-5.1 at CL 23058290.

This was regression tested against //UE5/Release-5.0 at CL 20979098 and is confirmed to not be a regression since the issue also occurs in this build.

Customer Description:

Plugin names with a minus character result in failure and perhaps with other special characters, but the GUI doesn't warn about it nor stop the user from attempting to create a new plugin. Perhaps it was intended to work with minus signs, underscore does work. 
Steps to Reproduce

Steps:

  1. Create a new C++ project.
  2. Go to Edit > Plugins.
  3. Click the Add button.
  4. Select Blank as the template.
    • Other templates also share this issue except for Content Only.
  5. Name the plugin with a "-" character.
    • e.g. Plugin-Name, PluginName-, etc.
  6. Create the Plugin.

Actual Result: Error, failure to create plugin.

Expected Result: Attempting to create a plugin with the minus character in its name should result in either an error warning about using an invalid filename or allow the user to successfully create the plugin.
