IntelliJ Freeze

[donaldww]

Describe the bug
A clear and concise description of what the bug is.

Editing a line that looks like the following causes the editor (IntelliJ) to freeze and the CPU to spike. The only remedy is to kill the editor.

alias Aggregator.{KV, DT, MP}

To Reproduce

1. Type in a line as per above.
2. Edit the line.
3. This happened on both a laptop and desktop.

The work around for now is to split into three separate lines:

alias Aggregator.KV
alias Aggregator.DT
alias Aggregator.MP

Expected behavior

Should work.

Desktop:

• macOS Big Sur
• Version 11.6

Elixir:

• Elixir 1.12.3 (compiled with Erlang/OTP 24)

Plugin:

• Elixir 11.13.0
• IntelliJ 2021.2
• IdeaVim 1.7.2

In the meantime, feel free to try out this latest local build I made to see if it fixes your issues.

It happens to me too after I upgraded to 12.1.0

I can confirm I am seeing this on 12.2.0
It is not consistently happening after I force quit, I will try and catch it today and drop a thread dump here.
