I am having this same problem as well. Every time I go to launch a mod-pack, the launcher disappears and reappears like nothing happened. I currently have the latest version of Java. I tried installing the Nvidia's driver downgrade to usually fix this issue, but my computer does not contain a Nvidia graphics card. On launch of a mod-pack, I am brought with a "B#349] SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder" error message and results back to the launcher menu. Here is the crash report https://pastebin.com/kLXYAp5K Here is the console log https://pastebin.com/HvzvhdqM Thanks for the help!
