Undefined Property Access in Tool Use Rendering

I'm getting this too, about once every thirty minutes. It's pretty much a show-stopper -- every Claude Code session gets interrupted by this bug and I have to quit it and start again, losing my context. It started after I upgraded to 1.0.38

Now I'll launch sub-agents to analyze the key project files. Let me focus on the core source files and important configuration files:

I shifted to a new Mac and thts when this issue happened for the first time. Unsure if related.

I am experiencing this as well. I tried upgrading to latest (1.0.39) using claude update latest to see if it was fixed and am continuing to get a similar error:

I downgraded to 1.0.37 and am no longer having the issue.

@dsargeant : Thanks, mate!!! That seems to have worked. Fingers crossed!!!
