Seems like a thread issue, on KFileItemModel::insertItems

```
m_items.clear()
```

Do you use splited views, did move around in your folders quickly ?
Comment 2 adec2011.ac 2023-02-19 18:58:20 UTC 
I can confirm this is happening to me too. Yes i do use split view and move files around a lot. Only started happening to me since the 18/2/23 update
