8.351 - Public Submission - Record edit link URL - error 500

Hello, just tested forum pack as public guest user. Topic submission and storage works. The message tells me about the "Record edit link"...

I tested submissions on different ways and locations: - Section menu - Submit here - Module "Submit Buttons" with different parameters

But all attempts result in:

Error 500 - View not found [name, type, prefix]: forms, html, cobaltView

Example URLs:
