Store 'No route found' error after update to Shopware 6.4.1:

Store ‚No route found‘ error after update to Shopware 6.4.1:

No route found for „POST https://dev.de/api/_action/extension-store/list“ (from „https://dev.de/admin“)

Someone has an idea, how to fix this?

I also have „No route found“ problems after an update and running the migration assistant. How did you solve your problem?

What confuses me a bit is that when changing the theme there is no longer a „No route found“ problem.

I remember in that time updates Store Extension created some issues for us.
