Hey. My modpacks on twitch stopped working a few days ago. They were fine and everything worked till now. My twitch is updated and normal Minecraft works fine. I play Minecraft 1.14 and it works fine I even use mods like optifine and a couple of others and again it works fine. At first, I thought that it was my internet problem however all other things work like Minecraft servers, youtube, and Netflix. When I try to open any modpack like RLCraft or FTB or SkyFactory it won't load. I don't think it is a problem with my ram as it worked before. (I have a Mac OS and have 8gb of ram total and have allocated 3.5gb to Minecraft/twitch) When I try to open a modpack it opens in the Jar launcher (1.6.91). I tried switching it to native but it doesn't work. When I try to open a modpack it just stays on the jar loading screen and won't load. Before It loaded after a few seconds now it could stay on the loading screen for hours and still nothing.
Below is the picture of the loading screen that pops up for me.
