[Bug]: Stuck on User Input Tool GUI #4060
Description
Before submitting
- I searched existing issues and did not find a duplicate.
- I included enough detail to reproduce or investigate the problem.
Area
apps/desktop
Steps to reproduce
When a provider goes away in the middle of a user input tool call, it's not possible to exit the UI and the session gets stuck:
- Closing the app and reopening it does not fix the problem
- Alpha or Nightly does not fix the problem
- Switching model does not fix the problem
- switching to a different conversation then back does not fix the problem
- cmd+R to reload did not help.
Expected behavior
When the provider goes away I should be able to dismiss the user input tool UI, or there should be an error. In claude code I can press escape to dismiss it.
Actual behavior
The conversation is trapped in a tiny sliver of the window while most of it is taken up by a series of questions that can never be submitted.
Impact
Blocks work completely

Noting that I launched claude code in the terminal and asked it to find the session. After resuming it asked me the questions again and it worked fine. I suspect the problem here is caused by the provider going away, but then can't be escaped from due to not being able to dismiss the user question tool GUI. I have no information to help explain why the provider went away, but dismissing the user input would have allowed me to recover the session in T3 Code or gather more data.
This would have unblocked me:

Thanks for the detailed report. This looks like the same issue tracked in issue #5454.
The original report describes a pending question that cannot be answered or dismissed after the provider disappears, and that survives app reopen and reload. Open issue #5454 covers the same dead-session question and restart recovery failure. The Claude teardown change prevents some new leaked requests but does not recover every already persisted card.
I'm closing this as a duplicate as part of an automated pass on all open issues. I linked this report from issue #5454 so its extra details remain available. This does not mean the underlying bug is fixed.
