Any logs appears and auto-refresh doesn't work

hi everyOne,
I update my expo version to the last and since this time, I have any logs appears in my command line, I tried to start with ‘npm start’ then ‘npm run android’, but no success.
And when I save, the project makes auto-refresh anymore.
I changed my expo like my older version (20) but it didn’t work.
Someone help me? (sorry for my english XD)

can you share your complete project? i can take a look at it.

this is a project for my society so I can’t, sorry for this. but even if I create a new project, It dit the same.
