[magicsk]

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

1. start the app
2. start the thread in project with codex
3. 2-x message will produce this error and even on restart its not possible to continue so you loose the whole thread, i added pictures this time but it happends sometimes also without them

• can be that 2-x message was after 10 or more minutes

Expected behavior

Should just normally resume and accept the message

Actual behavior

just this error message:
ProviderAdapterProcessError: Provider adapter process error (codex) for thread 64b6d081-e1e7-4683-935a-b60023dcb538: Invalid thread/resume payload: Expected { readonly "type": "userMessage", ... } | { readonly "type": "hookPrompt", ... } | { readonly "type": "agentMessage", ... } | { readonly "type": "plan", ... } | {
