I decided to reinstall Eclipse, because I was having trouble creating Maven archetypes while creating a Maven project.

I went to https://www.eclipse.org/downloads/

I clicked on "Download x86-64".

I downloaded the image.

I double-clicked "eclipse-inst-jre-mac64.dmg".

I dragged and dropped "Eclipse Installer" into Applications.

I went to Applications and double-clicked "Eclipse."

I launched into my workspace.

When I selected File->New->Maven Project, nothing happened.
When I selected File->New->Other ..., I got the dialog box.
When I selected Maven Project, I saw a blank "New Maven Project" dialog box.
(In previous installation tries, I would get an error message: "Cannot invoke "org.eclipse.m2e.core.ui.internal.archetype.ArchetypePlugin.getActiveArchetypeCatalogs()" because "archetypeManager" is null")

When I click "Next >," nothing happens.
I can create a standard Java project that uses Ant.

There are quite a few changes in m2e for the latest release.

You can ask a question specifically about m2e here:

https://github.com/eclipse-m2e/m2e-core/discussions

And you can open an m2e issue issue here:

Another thing I noticed today is that this might be caused by duplicate/inconsistent -Dosgi.requiredJavaVersion options like this 
-Dosgi.requiredJavaVersion=17
...
-Dosgi.requiredJavaVersion=11

If the one for Java 11 is last, I think anything requiring Java 17 willl be disabled. Edit the file to remove -Dosgi.requiredJavaVersion=11.
