I have the same issue, but I found a temporary solution.

Vs code:

• flutter build ios --no-codesign

get path like - /build/.../runner.app/

Flutter.framework floder inside run below code:

• dsymutil Flutter -o Flutter.framework.dSYM

get (Flutter.framework.dSYM) file to paste into the xcode => archive => package content => DSYMs floder

Revalidate the file pasted in the same build
