I get two error message when I start OMedit:

@Micha109GE, v. 1.15.0 is not going to be released and will be cancelled, see https://trac.openmodelica.org/OpenModelica/milestone/1.15.0. Please try the latest 1.16.0 nightly instead, and please report if you still have the same issue.

Thank you!

Note that ModelicaAdditions is almost 19 years old. You need to use the command-line omc with --std=1.x to have any use of it, and even then I'm not sure if it works (especially if it's a dependency of other libraries; the Modelica specification at the time was not as clear as it is today). Don't use it for new development; the latest standard library should have everything you need.
