Summary:
Deleting a chat from Recents can fail for some entries within the list for seemingly no reason. At times the Windows desktop app will show a error "Failed to Delete Chat" as a red slide down message at the top of the screen. The chat list item remains in the "Recents" section in ChatGPT mode. This can occur for chats within the list that have no error icons next to the chat name, but also can occur for chats that do have a red "info" icon showing up next to the chat name in the Recents list.

Steps to reproduce:
Open ChatGPT in the Windows desktop app
Select a chat under Recents (example: “Lease Repair Options”)
Delete → confirm “Delete chat”
Chat sometimes remains in Recents
Click the stale entry or try deleting it again

Expected:
Chat disappears from Recents immediately and stays removed.

Actual:
Stale chat remains in Recents and cannot be removed. Errors include:
“Could not load this ChatGPT conversation”
“Failed to delete chat”
{"detail":{"message":"Conversation has been deleted. Start a new chat.","code":"conversation_deleted","can_retry"}}

Frequency/Impact:
Intermittent; long-standing; leaves unusable “dead” items in Recents and creates confusing load/delete failures.

Troubleshooting attempted (no fix):
Force quit/relaunch, Sign out/in, Update desktop application

Attachments:
3 screenshots (delete confirmation; stale entry with failures; server response confirming conversation already deleted).

What is the expected behavior?

Chat disappears from Recents immediately and stays removed.

Additional information

Start by reproducing the delete and reload flow in the Windows desktop app using a chat under Recents, including an entry that reports conversation_deleted. Trace the Recents handling for failed loads and deletes; done means deleted conversations disappear immediately and cannot reappear as stale entries, with the reported failure messages no longer occurring.
