I recently wrote a blog post specifically for that issue. As it is a very broad topic with a lot of possible reasons, I just outlined the most popular reasons:

Deleting repoinit folder from my AEM instance fixed this issue for me. Either you can run below command

rm -rf crx-quickstart/launchpad/config/org/apache/sling/jcr/repoinit OR delete the folder manually.

Blog post which Jorg mentioned, also talk about repoinit as one of the reason for getting this error.
