RubyMine Auto Completion Freeze

Problem

JetBrains RubyMine is an IDE for Ruby development.

RubyMine has the Auto Completion feature.

Recently, the RubyMine got stuck when the completion pop up on my macOS. I have to force close it from Activity Monitor.

Restart RubyMine can not fix the issue.

Solve Progress

Disable ML completion or EditorConfig support (Fail)

I found the issue ticket: IDEA sometimes complete hangs indefinitely when opening autocomplete modal

Disable ML completion

Disable EditorConfig support

They both do not fix the issue.

Clear RubyMine Cache (Works)

I found the community post: WebStorm 2023.2 hangs

Follow the comment, I deleted the files under RubyMine Logs folder and restart RubyMine. But it does not work.

Note：

• Remember replace <macOS Username> to your macOS Username.
• Remember replace RubyMine2023.2 to the version you are using.

/Users/<macOS Username>/Library/Logs/JetBrains/RubyMine2023.2/

I tried another comment: Delete the RubyMine caches.

I deleted the files under RubyMine Caches folder and restart RubyMine.

Note：

• Remember replace <macOS Username> to your macOS Username.
• Remember replace RubyMine2023.2 to the version you are using.

/Users/<macOS Username>/Library/Caches/JetBrains/RubyMine2023.2/caches/*

Then I fix the issue successfully.
