About chrome manifest version 3?

I try to run with yarn start:mv3.
And then add the MetaMask plugin to chrome by choosing directory.
but it get some error as below:


I have check the MetaMask release versions. It seems that the latest release version is still using manifest version 2.

So I want to ask whether the yarn start:mv3 is ready or not. How can I solve the errors.
And when will MetaMask release a plugin using manifest version 3 as an official standard release.

other errors:
