Renderer crash when opening session - infinite loop in constructMessageRows #29149

Steps to reproduce

1. Open OpenCode Desktop
2. Click on a specific session (Named: Looking into Playwright page UI/UX...)

Expected: Session opens and displays messages normally
Actual: Renderer becomes unresponsive and eventually the desktop application crashes

Description

Stack Trace:

renderer unresponsive { window: 'main', currentURL: 'oc://renderer/index.html' }
  at Object.constructMessageRows (session-oGzwM_29.js:21244:55)
  at Array.some (<anonymous>)
  at Proxy.reduceRight (<anonymous>)
  [infinite reactive loop in SolidJS computation]

Notes:

• Only affects this one particular session
• All other sessions load/work fine
• Issue persists across multiple app restarts
• Debug logs attached show the renderer thread getting stuck

Personal Notes:
Everything in this issue, I had OpenCode help me write.
I'd just like to point out that the session in question probably is pretty big, and that is likely the culprit.
I used Owl Alpha (free) from OpenRouter to generate the data. I don't know if it makes any difference.
I had the Playwright MCP enabled - but seeing as it kept crashing, I tried without it being enabled. It still crashes in the exact same manner
