It is happening all the time here now.
Claude Code 2.1.49 as a VS Code extension.
Windows 11 ARM.

[matsvw]

Same here. Several times today. Seems to pick up quite well if you just give some input like "continue".

Claude Code 2.1.49, VS Code 1.109.05

Also using Windows 11 ARM.

[awshima]

Exactly, I'm using "resume" :)

[ddalmolin]

Same problem (windows 11 with snapdragon x elite).
I downloaded a previous version.

[lluisterrado-cpu]

Same here (also Snapdragon X).

[john-mckillip]

I am experiencing the same. Latest version of the VS Code extension. Windows 11 Snapdragon(R) X 12-core X1E80100 @ 3.40 GHz (3.42 GHz)

I looks stable this morning, 1h so far without the error.
