Based on your screenshots, it appears to me that you're passing the results of your Get Records element directly into Create Records. Even if this worked, I don't think it's going to do what you want, but the core problem seems to be that your sObject collection variable contains Ids from the queried records.
Your screenshot shows
For each item in the collection, make sure the ID is blank.
In the Fast Create element documentation, there's the same injunction with some additional detail:
The sObject variable or collection that you want to use to create the record or multiple records. The object types must match, and each ID field must not have a value.
Emphasis mine. Here, additionally, the object types do not match; the records in your collection variable aren't the same as the type you wish to create.
I think you'll need to create a second sObject collection variable, and then loop over your collected records to create new records of the type you want. Within the loop, you'd populate each new record with the fields you've chosen from the source sObject - which would not include their Ids, so those new records would have their Id field blank as the system expects. They'd also be of the correct sObject type.
Then, you'd pass that second collection to Create Records.
