Startup pop-up crashes the engine in Commandlet mode

Describe the bug
Title says it all.
To Reproduce
- Enable the plugin
- Remove the .ini file used to determine first launch (simulate a first launch)
- Launch a commandlet
Expected behavior
The plugin does not crash the engine.
Environment (please complete the following information):
- Unreal Engine version: 4.26 and 5.00
- Operating System: Windows 10
I'm really sorry for this, I really tried to make this popup frictionless...
I tried to set up a commandlet, but I'm not familiar with such a feature.
Here's what I did:
- Download this repo (https://github.com/ue4plugins/CommandletPlugin) and put it inside the Plugins folder of my project
- Create a .bat file to run the commandlet
Here are the versions I tested for the .bat file:
"D:\Program Files\Epic Games\UE_4.26\Engine\Binaries\Win64\UE4Editor-Cmd.exe" -project="D:\Library\Documents\Unreal Projects\PluginTestFPS 4.26\PluginTestFPS.uproject" -run=HelloWorld
"D:\Program Files\Epic Games\UE_4.26\Engine\Binaries\Win64\UE4Editor-Cmd.exe" "D:\Library\Documents\Unreal Projects\PluginTestFPS 4.26\PluginTestFPS.uproject" -run=HelloWorld
"D:\Program Files\Epic Games\UE_4.26\Engine\Binaries\Win64\UE4Editor-Cmd.exe" "PluginTestFPS 4.26" -run=HelloWorld
"D:\Program Files\Epic Games\UE_4.26\Engine\Binaries\Win64\UE4Editor-Cmd.exe" "PluginTestFPS" -run=HelloWorld
But it always ended with this error:
Do you have any idea what command line I should use to use the commandlet?
I cannot package on a headless Linux server due to the popup, it causes a malloc error with slate. I had the same thing with another plugin (albeit they had it in a separate 'module' so it was easier to disable via the .uproject file). I have since written scripts to remove ElectronicNodes from projects upon submitting to CI/CD servers.
For an example of commandlet that we tried and failed, you can run UE4Editor.exe <ProjectName> -run=loadpackage [arguments].
@CanisHelix Sorry for that... You could also have disabled the popup in Edit/Editor Preferences/Electronic Nodes
I'm going to check if the engine is in headless mode before displaying any popup. Again, I'm really sorry it made that much trouble...
@hugoattal That might work, I'll see if I can get that flipped in the .ini before the CI/CD runs.
Ok, so I added a check that might fix the issue
Unfortunatly, I wasn't able to test it (or to make commandlet works), so... finger crossed
