Issue with updating 4.4.11 to 4.4.12

Hi there,
a partner has the following issues with the update. He is experienced, but before he is trying to debug it - is this a known issue and will there be fixes for the update?$VERSION/composer.json is “broken”, it often says “” instead of “4.4.12”, I can fix that, but it doesn’t speak in favour of QM

sudo -u xxx php8.0 /usr/bin/composer update

Your requirements could not be resolved to an installable set of packages.

Problem 1
- Root composer.json requires mautic/core-composer-scaffold 4.4.12, found mautic/core-composer-scaffold[dev-RCheesley-patch-1, 3.x-dev, 4.x-dev] but it does not match the constraint.
Problem 2
- Root composer.json requires mautic/core-project-message 4.4.12, found mautic/core-project-message[3.x-dev, 4.x-dev] but it does not match the constraint.

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

“-W” does NOT solve the problem.
