Editor crashes on launch

Hey I bought the “Spline: Ropes - Hoses - Sci-fi” content from the markedplace and added it to my project. I tried launching it several times but it crashes with this error message:

Go ahead and open your Unreal launcher and verify your version of Unreal Engine.

I went ahead and checked the versions the plugin supports and it looks like you should be fine. Are there any reasons you’re staying on version 4.11? I’d suggest updating and migrating your projects to the latest version.

If the verify doesn’t work I’d suggest deleting the Spline: Ropes - Hoses - Sci-fi pack and seeing if your engine opens up afterward.

Hey, the main reason for why I still stick for 4.11 is all the plugins I use. They’re not updated yet. I works abselutely fine in 4.12 but not in 4.11… no worries though I’ll continue in 4.12

Tank you for the help XD
