I can't invite my friend in my world and my friend can't invite me

When i invited my friend It appears to me “there was a problem with your connection multiplayer hosting has stopped and will need to be restarted”

After that I restarted the world and it didn't fixed the problem then i restarted the game and didn't fixed then I restarted the mobile and it didn't fixed the problem

And I tried many ways to fix this problem in YouTube, TikTok and it didn't fixed

Please fix this problem because I want to play with my friend and thanks
