Hello
there is one issue with the info you provided, it's from Xcode12.5 beta.
And beta license agreement forbids sharing output of beta version of compiler&co
So we can't say we have issue with newer xcode beta until that beta went public & released.
Fixing issues you found now will mean someone have violated xcode beta license agreement and made these issues public.
