What's Wrong?

The error message: "Failed to load session" shows when trying to load my last session
The session URL or ID if visible: https://claude.ai/code/session_011KQCHtToWENAJjcbZFXWU8
When it started happening: The same day I ran out of credits around Dec 14th but I'm in a new month now with new credits so it should work
Browser/OS info: Chrome Version 143.0.7499.170 (Official Build) (64-bit)

I was working on "Set up Telegram Channel connection feature" chat and when I first clicked on it it seems to be trying to load but then fails.
The session was on branch claude/telegram-channel-connection-011KQCHtToWENAJjcbZFXWU8
Session failed to load after previous work was completed

What Should Happen?

It should load successfully like all the times before so I can continue the coding conversation. Since Claude Code doesn't seem to show exactly where I left off after I reload it day over day it's crucial I get this session working again so claude and confirm where we left off and continue the work.
