Hi. I'm having a similar problem. I'm trying to make a modpack and everymod crash on loading. I tried troubleshooting in myself by making the modpack one mod at a time and whichever i try, i always get rejected on lauch either exit code -1 or a big crash report(see below)
I have no idea why and it starting to irritate me tbh.
Here's the log
If one of you have an idea...
