Why is composer deleting and reinstalling core?

I am running Drupal 9.2.4 on Lando on Mac Big Sur. When I use composer to install a module it first deletes core.

Removing package drupal/core so that it can be re-installed and re-patched.
 - Removing drupal/core (9.2.4)

Then it reinstalls it.

 - Installing drupal/core (9.2.4): Extracting archive

If the module fails to install, no core!

I think these are the relevant lines from composer.json.

"drupal/core": "^9.2.4",
"drupal/core-composer-scaffold": "@stable",
"drupal/core-project-message": "9.2.4",
"drupal/core-recommended": "@stable",

Any ideas as to why this is happening and how to prevent it from happening?
