Cannot create Run Profiles in Rider: Invalid Exe Path error

Problem

The "Run" button was unavailable in JetBrains Rider after moving the UE5 and Rider installation to a new machine. Attempts to set up a Run Profile resulted in an "Invalid Exe Path" error, and the necessary field for correcting the path was not editable.

Cause

Project files after directory transition were not re-generated

Resolution

1. Generate Project Files:

   • Locate the .uproject file for the game project in Windows Explorer.
   • Right-click the file and select "Generate Visual Studio project files."

2. Or open the project in Rider via the .uproject File:

   • Use Rider to open the {Game}.uproject file (instead of {Game}.sln).
   • This process will generate the necessary project-files;

By opening the .uproject directly, Rider correctly identifies and configures the settings needed for the project, resolving the issue with the "Invalid Exe Path" error.

Ensure to follow these steps if a similar situation arises to set up a working development environment in Rider after a migration.
