[Bug] Claude Code freezes intermittently on Windows Terminal

[isaac-bender]

Bug Description
I'm running Claude Code in Windows Terminal. Recently, it's been freezing for several seconds at a time. It seems to have started happening within the past few days. I tried removing everything in the cache older than a couple of days and it didn't seem to help. I've added my project dir and claude's cache dir to antivirus exceptions, rebooted, /cleared, tried all the obvious stuff.

Environment Info

• Platform: win32
• Terminal: windows-terminal
• Version: 2.0.50
• Feedback ID: 9e22e670-4bfe-4ea9-9e68-9956e06aa8b8

2.0.50 is very buggy, causing lag and it seems to edit entire file instead of targeted edits. Multiple bugs were reported on this.

So the workaround is to rollback to 2.0.49

Steps:

1. Windows Search for: Edit the System Environment variables -> Environment Variables -> New system variable -> name: DISABLE_AUTOUPDATER value: 1.

2. npm install -g @anthropic-ai/claude-code@2.0.49

I am in version 2.0.53

I am having a similar problem. Claude will freeze in thinking mode for several minutes or hours when.

1. I do not enter anything into the keyboard for a long time.
2. Change focus outside of terminal.

It does not come out of this mode until I reestablish windows focus and hit a key on the keyboard.

This happens multiple times a day. I have had it happen on both Opus and Sonnet

You said you were in 2.0.53, but your last line mentions 2.0.50. Check it up again

Same, on a Mac running inside a Jetbrains IDE terminal window. The animations stop, everything stops.. Just for a few seconds. But every few seconds.

Same here on Windows 10 using claude-code 2.0.47-2.0.53, but only when using WSL. Powershell or CMD have these periodic freezes for some reason.

From what I can see it shouldn't be related to the terminal, but instead to the shell or something else. Getting same results for all 3 shells using both Windows Terminal and ConEmu (via Cmder), and others have the problem on Mac -> bash/sh being the common denominator?

Additionally, observed that when I start claude and begin typing, then as soon as it freezes, a python process will jump to the top in my CPU sorted taskmanager. If I keep typing, the freezing will however resolve and seem to fully stop after about ~30 seconds.

For the time being I just use CMD, check the difference compared to WSL here: (edit: saw it too late, but enabling thinking in CMD makes no difference)
