Can't add data on a certain table

[SGC-Dev]

Hello guys, this error always comes up when I'm trying to add data using a pop up form on an interface level: Worker responded with {errorCode} for {path}, {action}, {modelClassName} (Please see the First Image)
Also when I'm trying to add data manually on the backend, an error message also pops up (please see second image). Both of this are occurring on the same table. I'm the author/owner of the base.
What do I do? Thanks in advance!

Hm, might want to open a support ticket directly with that error tooltip.  I take it you've got no permissions set for fields in that table or that table itself as well, right?

Yes, there are no permissions set on any fields and on the table itself. I've already sent a ticket to the support. Thanks for the response!
