[BUG]: Stale read from <Show> crash when trying to access subagent task

Description

Windows Desktop App

I'm working with an "Orchestrator" primary agent, he spawns subagents, sometimes when I try to access a subagent right after he got created I get a critical error:

Error: Stale read from <Show>.

No response

OpenCode version

v1.2.17

Steps to reproduce

I start a new session, start working with it by describing a task that requires a custom subagent to be used, after thinking the model does execute the task tool and spawn the subagent, I click on the label to go into its session and I instantly get the crash.

This issue might be a duplicate of (or related to) existing issues about subagent session navigation. Please check:

Clicking on Task tool no longer navigates to subagent session #15769: Clicking on Task tool no longer navigates to subagent session (click navigation broken after BlockTool→InlineTool refactor)
bug(tui): subagent navigation broken for nested sessions and imprecise for multiple concurrent tasks #15972: Subagent navigation broken for nested sessions and imprecise for multiple concurrent tasks (same root cause, same commit)

The crash you're seeing when clicking into a subagent session may be related to the same refactor introduced in commit 90270c615. If you can confirm whether the crash is reproducible via the keyboard shortcut (Ctrl+X Down) as well, that would help distinguish whether this is a new crash on top of the navigation issue or a separate problem.

Can be still reproduced with 1.2.20

Could you test on latest and let me know if you're able to reproduce? Also, would love to know how you reliably reproduce, been lacking that on our side.

It seems to be fixed with 1.2.22.

To reproduce the issue all I was doing is:

Have a couple of session on-going on "local" with workspaces enabled
Use an Orchestrator primary agent which delegates work to subagents
After making a prompt that queries a couple subagents, I just go ahead and click on the subagent label to go into its session
Switching between subagents eg back to orchestrator -> go into subagent task session was leading "sometimes" to this issue (often tho)
