Hello, since yesterday morning we can no longer create XInvoices in the accounting department. The invoices created last week can be called up and the X-invoices are also available. However, if you reset these invoices to draft status, nothing can be created for them either. So something unknown must have happened in the background. An error during entry should therefore be ruled out in this way. Who has any idea what may have gone wrong and where I can look?

If I set the format to, for example, BIS Billing, everything works normally.
