Update core 10.0.x to 10.1.x not possible

Perhaps it is a problem in composer.
If I want to install Drupal core 10.1.x the installation failed with the remark that I need an other version of Linkit.
If I want to install Linkit the installation failed with the remark I need an other version of drupal core.
It looks like that both have to be installed at the same time.
The command "--with-all-dependencies" don´t help.

I´ve tried all recommended update commands on the sites of Drupal Core and LINKIT.
The code of composer.json follow here:
