Can't install specific version of gcc-mingw

I need gcc-mingw-w64 version 9.3.0 for a project to compile correctly. I am running hirsute. For this release the gcc-mingw-w64 version is 10.0 something. I already added archive.ubuntu.org focal to my sources.list. But when I run sudo apt update and then sudo apt install gcc-mingw-w64=9.3.0-7ubuntu1+22~exp1ubuntu4 -s the dependant packages are still installed from the hirsute repo:

How can I fix this?

You are doing in the right direction, but forgot two things - add main pocket for focal and to supply -t=target_release option to APT.

So complete solution is the following:

sudo add-apt-repository "deb focal main universe"
sudo apt install gcc-mingw-w64=9.3.0-7ubuntu1+22~exp1ubuntu4 -s -t focal

Note: -s should be removed as we now have correct package origins:
