Hi @cindyxyz96,

Have you looked into https://github.com/zauberzeug/nicegui/issues/3028 as the warning suggests? Without seeing your code, it's hard to tell what's going on. But there might be some global logger that is updating multiple ui.log elements. This causes the logger to hold these elements and their client object, causing a memory leak.

I'll close this issue as stale. Feel free to re-open it once you've got new information for us. Thanks!
