Title "RuntimeException: No OpenGL context found in the current thread."

Launcher Type MultiMC

Modpack FTB Beyond

Modpack version 1.11

Have you modified the pack? No

Details of the issue I'm on Arch Linux 4.13 running the newest driver (nvidia-340xx) for my admittedly very old GeForce 9800GT, but I did play FTB modpacks with this setup already.

FTB Beyond crashes right after starting. Vanilla Minecraft itself runs perfectly fine.

While researching I found similar reports from years ago, yet they didn't help. I tried JRE7, JRE8 (openJRE and Oracle) and JRE9. JRE7 and JRE9 crash with version related issues, while openJRE8 and OracleJRE8 both report this "OpenGL context"-issue. I am receiving an identical error message with the legacy FTB-Launcher.

I would be very thankful, if someone was able to help me.

Okay, so my FTB Beyond instance now starts as it's supposed to be.

While I still don't know what caused the issue I had, here's what helped me:
I updated MultiMC through its development channel and reinstalled the modpack I downloaded from Curseforge with MultiMCs integrated downloader.
(Before I downloaded the modpack via the lagacy FTB-launcher and had MultiMC track my installed FTB instances.)

Basically I tried "turning it off and on again" and it worked. ¯\_(ツ)_/¯

So I hope this might help anyone running into a similar problem.
