WPMUDEV host urls in database instead of my domain

My emails are for an example me@mysite.wpmudev.host
not me@mysite.com
just for exemple
I need to do a search and replace in database
For the email I have tried to use WP Mail SMTP plugin, I can't receive any order confirmation from wp though customers receive the mail order confirmation not me.
However not only the email I need erase all entries in database and replace wpmudev urls my domain like mysite.wpmudev.host to mysite.com
I'm trying to do that since morning, and it's very complicated. Site front seams ok, the problem is in the database
Please check the screenshot shared in the chat.
