The listener for function 'IotHubTrigger' was unable to start. IoTHub

I managed to solve the problem, in AzureStorageExplorer under local/Emulator/blobcontainer/azure-webjobs-eventhub & host, removed everything that had to do with iothub/eventhub, and did a restart on the computer and boom so it started to work again.

Thanks to the people who left a comment!
