In an experimental project using PHP 8.0, I've tried to install the symfony/profiler-pack but it's not possible because of the PHP constraint sets in the composer.json.
However each dependency of the pack seems to be PHP 8.0 ready. I've installed all packages individually and the profiler works.
I think, you should remove the PHP constraint and let Composer resolving dependencies with the required dependencies constraints.
