This issue happend midway.
I prompted Claude with 38 lines to edit a class.
Claude created a plan and clarified information which was already written in my prompt, but this is not the issue.
After doing half of the implementation, it crashed with this error, then wrote

1 tasks (0 done, 1 in progress, 0 open)
