I attempted to fix it with yarn install but nothing change and show that they all up-to-date

yarn install v1.16.0
[1/4] Resolving packages...
success Already up-to-date.
Done in 0.85s.

I can't understand what's the reason that causes this and how to fix it.

Yarn doc:

https://classic.yarnpkg.com/en/docs/cli/check/

NOTE: The command yarn check has been historically buggy and undermaintained and, as such, has been deprecated and will be removed in Yarn 2.0. You should use yarn install --check-files instead.

yarn install --check-files
