after upgrade, I can't load session I was working on.

after upgrade, I can't load session I was working on. retry, restart, resume none of them working.

please make it never fail, it is fine to lose some history but making it to lose whole session doesn't make sense when there are a lot work in progress there.

it shouldn't fail fast. it doesn't make sense to lose whole session just because it couldn't figure out some small stuff.

首先，在 Windows 10.0.26200 上的应用版本 1.1.9 中，于 /chat 路径尝试重试、重启和恢复受影响的会话，以复现该故障。当与升级相关的会话加载失败不再丢弃整个会话，并且任何无法恢复的历史记录丢失都能在不立即失败的情况下得到处理时，即视为完成。
