Logic app not triggering when a blob is added or updated in one tenant, but works in another.

I have created a logic app in Azure that should trigger when a blob is added to a container.

And here are the storage account containers:

The logic app and the storage account are in the same resource group.

I have re-created the connection from the logic app to the storage account several times to confirm it's correct, and I have also given the logic app contributor rights to the storage account (although I don't think that should be necessary). When I add a new blob to the sysvak container, the logic app does not trigger at all. It does not matter which directory inside the container I place the blob in. No runs appear in the run history so there are no logs to examine.

I have created the exact same setup in another Azure tenant, literally copied the code word for word with the exact same containers, and there it works perfectly. That is however not the tenant I need the logic app in, so I need to get it working in the first tenant. What could be wrong here?

Possibly related, I have also been having some other issues with this logic app. I am sometimes met with this error message when trying to view the list of workflows:

And this error message when trying to view the workflow designer:

It's seemingly random when the error messages appear and when it loads fine.

In the logic app that is not working there is a bunch of messages in the app insights log saying that the listener has stopped
