Flow Designer permissions issue

[Victor53]

Hi, I'm having some flows, which at some point will try and generate some catalog tasks, if some verification fails, namely, if a record field is empty, whatever, doesn't matter.
The flow runs as a System User, yet when the catalog task step is reached, I'm getting this error:
[The requested flow operation was prohibited by security rules.]

I don't understand what is causing this behavior.
Thank you for your help

Ideally with system user it should not give security issue.

Is this happening all the time or intermittently?

If my response helped please mark it correct and close the thread so that it benefits future readers.

It is happening all the time unfortunately : (

did you check any ACL is blocking the insertion of catalog task since you are unable to create task?

share flow screenshots.
