[BUG] IllegalStateException: EDT threading violation when approving all parallel edits in PHPStorm plugin

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

I got prompted by claude code if I wanted to approve each edit that was going to be made one-by-one or all. When answering all, it made the edits in parallel, but the PHPStorm plugin crashed. The edits were made without any issue, but there was no approve prompt.

Platform:

• Windows 11 with Native Mode for development in WSL
• PHPStorm 2026.1.1
• Claude Code Beta Plugin 0.1.14-beta

What Should Happen?

I do not know really, probably to just make the edits.
