@solonovamax:
Enabling the plugin in versions 2024.2 or 2024.1.6 causes IntelliJ to not open what so ever. Unsure if this is an issue with some configuration on my end, however I know for sure this is caused by the vineflower plugin.
This causes IntelliJ to remain stuck on the splash screen indefinitely.

I believe it has something to do with the "automatically downloads the latest vineflower updates on IDE startup" feature.

[...]

@solonovamax:
This only started occurring really recently and had never happened before this

@Earthcomputer:
Yeah I think recent intellij updates have made the problem worse. I've unfortunately had to disable the plugin myself. Will be fixed soon.

I'd like to reopen this one, the version after the fix also causes the UI freeze:

Yeah, I'm really not sure why. But it's being tracked in #20 now.
