When I try to launch Minecraft via the Twitch app, it launches with the old JAR launcher, which doesn't properly work with modpacks on my computer. It seems like there's a setting for using the native launcher (in Settings --> Minecraft), but whenever I select it, it switches back as soon as I leave the page. Any solution for this?
A few key points:
-I'm on MacOS Catalina, version 10.15.6 (which should be the latest version.)
-In the Minecraft settings in the Twitch app, it says the Java version it's using is 220.127.116.111 (64 Bit), which I redownloaded today just to make sure. I can also select 18.104.22.168 (64 Bit). Occasionally, when I check on this settings page, it says it isn't detecting Java.
-I've checked plenty of other sources in an attempt to fix this, and none give a solution that works for me.
