IMAP-Email works only 1 time

Questions

Hey!

I am using the Email Trigger (IMAP) Node to check incoming mails and forward them into an ai agent to analyze them. My Workflow works exactly 1 time.
After that I receive this error message:
Problem in node ‘Email Trigger (IMAP)‘ Search option argument must be a Date object or a parseable date string

I can reproduce the issue with restarting the n8n container. I can execute the workflow another time.
I do not have any custom rules activated.
It does not matter if I use in the format section RAW / simple / resolved
Here is a screenshot of the configuration:

The whole workflow looks like this
