React-Native tabs navigation bug: automatically returns to the first bottomtab visited

if I navigate in a top tab inside the bottom tab 1, and then I try to go to the bottom tab2, after a few seconds it brings me back to the initial bottom tab 1

these are my dependencies: "dependencies": { "@react-native-async-storage/async-storage": "^1.17.3", "@react-native-community/cli": "^6.4.0", "@react-navigation/bottom-tabs": "^6.3.1", "@react-navigation/drawer": "^6.4.1", "@react-navigation/material-bottom-tabs": "^6.2.1", "@react-navigation/material-top-tabs": "^6.2.1", "@react-navigation/native": "^6.0.10", "@react-navigation/native-stack": "^6.6.1", "accordion-collapse-react-native": "^1.1.0", "pushy-react-native": "^1.0.22", "react": "^17.0.2", "react-native": "^0.68.2", "react-native-background-fetch": "^4.1.0", "react-native-background-geolocation": "^4.7.1", "react-native-bootsplash": "^4.1.4", "react-native-gesture-handler": "^2.4.1", "react-native-in-app-review": "^3.3.3", "react-native-linear-gradient": "^2.5.6", "react-native-modal": "^13.0.1", "react-native-pager-view": "^5.4.15", "react-native-paper": "^4.12.0", "react-native-reanimated": "^2.6.0", "react-native-render-html": "^6.3.4", "react-native-safe-area-context": "^3.4.1", "react-native-screens": "^3.13.1", "react-native-tab-view": "^3.1.1", "react-native-vector-icons": "^9.1.0", "rn-fetch-blob": "^0.10.13" },
