Hi, could you include the whole thread dump? A deadlock usually involves multiple threads blocking on each other.

[Earthcomputer]

Also, does this happen consistently on a particular class, which would make it easy for me to reproduce the problem?

[Rubydesic]

I don't know what causes it or how to reproduce it. Full thread dump attached

Bumping to say that I'm having the same issue. It happens seemingly on random projects? I full cleared cache and .idea files from my project that had the issue, and it was freezing on the index step every time.

I had decompiled a kotlin class in said project, if that helps at all.

[halotroop2288]

I get a similar issue whenever the plugin is installed. This issue has persisted through a complete reset of my IDE.

I get a similar issue whenever the plugin is installed. This issue has persisted through a complete reset of my IDE.

I believe it has something to do with the state of the .idea folder (so the state the project gets loaded in), I can delete it to resolve this

[calmilamsy]

It persists through cache invalidation and a cleared .idea folder for me.

[wagyourtail]

It persists through cache invalidation and a cleared .idea folder for me.

as in your ide still instantly crashes after deleting .idea? or you have to actually start doing things for it to crash again?

[calmilamsy]

It hangs at the end of indexing libraries.

[gmitch215]

+1, hangs while indexing

[Desoroxxx]

Any progress on this?
