Describe the bug
I Can never seem to even install, or run, a Modpack with Minecraft game version 1.20.1. I have had this issue for years and always thought it would resolve itself. I have no clue how to replicate it. I suspect the problem is with the my Java installation but I do not know how to safely reinstall it without breaking anything. When I do attempt it simply states "Loader setup failed" and copying details provides a massive wall of text.
