New My app Vault widgets are gone after the app starts again

[iWisp360]

After i knew the posibility of adding apps widgets to the app vault, the replacement of google discover in MIUI EU, I added my favorite widgets to app vault to free my home screen, but after the app vault starts again it's process, the widgets gets deleted. To reproduce the bug just add app widgets to the app vault, like a calendar from android widgets, and then force stop the app vault(don't delete any app data or clear cache, just force stop) and look up the app vault again. My device is Redmi Note 12 4g(tapas) and i'm using the xiaomi.eu ROM V14.0.12
