For Croatia (and possibly Albania and North Macedonia) a single Schengen Visa C is not a valid visa
that was why you were refused entry and sent back to Slovenia.
Slovenia should have cancelled their Schengen exit stamp.
Legally you did not leave the Schengen area during this process.
There should be no negative SIS entry for that trip.
The fact that you now have had a new visa issued is also a sign that your travel history is ok.
This should not cause any problems on reentry.

No, you're good for the Schengen states with your current visa. You can even enter Croatia on it since it's a multi visa.
