Description

-The editor will crash when opening a project with the Renderdoc Plugin enabled while the user has Renderdoc installed on their machine. Uninstalling Renderdoc allows the project to open without crashing but this is not a great workaround as they will be unable to use Renderdoc with other applications.

This does not reproduce in //UE4/Release-4.23 cl 10478456 so this is a regression.-

This is not an Unreal specific issue. It's a bug in the 1.10 version of Renderdoc, and has been reported here. Work around is to downgrade Renderdoc or get a nightly build here: [Link Removed]

Steps to Reproduce
  1. Go to Renderdoc.org and download Renderdoc for your operating system
  2. Install Renderdoc to your machine
  3. Launch UE4Editor and create a new project
  4. Go to Edit > Plugins
  5. Enable the Renderdoc Plugin
  6. Restart the editor

Result
After restarting the editor will crash on startup

Expected
Users should be able to open projects with the Renderdoc Plugin enabled if they have renderdoc installed on their machine.

Workaround
Uninstall Renderdoc from your machine.
(This is not a great workaround because this means the user cannot use renderdoc with other applications without uninstalling/reinstalling every time they want to access their project)
